1.2 volts power supply

This switch mode power supply circuit require an input voltage range , between 4.5V to 16V,and will provide a very stable output voltage of 1.2 volt . The LTM4627 supports an output voltage range of 0.6V to 5V, set by a single external resistor , so you can modify the output voltage .


High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.

Simple mixer circuit – Common base

The simple mixer schematic is built on common base principle, where input voltages are transformed in alternative currents wich are summed to form the alternative current component for the collector. The total amplification is R6 - Ri, where Ri is one of the input resistors. I’ve build this mixer for a little transmitter and works great.

str6707

The STR-S6707, STR-S6708, and STR-S6709 are specifically designed to meet the requirement for increased integration and reliabil- ity in off-line quasi-resonant flyback converters.  These devices incorpo-
rate the primary control and proportional drive circuit with a third- generation high-voltage bipolar switching transistor.

Crucial system parameters such as maximum ON time and OFF
time are fixed during manufacture.  Local control circuit decoupling and
layout are optimized within each device.
Cycle-by-cycle current limiting, under-voltage lock-out with hyster-
esis, over-voltage protection, and thermal shutdown protect these
devices during all normal and overload conditions.  Over-voltage
protection and thermal shutdown are latched after a short delay.  A
versatile triple-level inhibit circuit includes the OFF time synchronization
required to establish quasi-resonant operation.  The inhibit function has
also been expanded to initiate operation in stand-by mode in which the
power supply delivers a small fraction of the steady-state output power.
The dual requirements of dielectric isolation and low transient thermal
impedance and steady-state thermal resistance are satisfied in an over-
molded single-in-line power package.
Proven in substantial volumes, these devices and their fixed-
frequency counterparts represent a significant advance in off-line SMPS
reliability growth and integration.


FEATURES
  Quasi-Resonant Operation for Low EMI and High Efficiency
  Output Power to 220 W
  Low-Power Output Standby Mode
  Pulse-by-Pulse Over-Current Protection
  Latched Over-Voltage and Thermal Protection
  Third-Generation Switching Transistor with Proportional Drive
  Maximum ON Time and Off Time Set During Manufacture
  Internal Under-Voltage Lockout with Hysteresis
  Over-Molded SIP with Integral Isolated Heat Spreader

MAX515 5V, Low-Power, Voltage-Output, Serial, 10-Bit DACs

The MAX504/MAX515 are low-power, voltage-output, 10-bit digital-to-analog converters (DACs) specified for single +5V power-supply operation. the MAX504 can also be operated with ±5V supplies. The MAX515 draws only 140µA, and the MAX504 (with internal reference) draws only 260µA. The MAX515 comes in 8-pin DIP and SO packages, while the MAX504 comes in 14-pin DIP and SO packages. Both parts have been trimmed for offset voltage, gain, and linearity, so no further adjustment is necessary.
The MAX515’s buffer is fixed at a gain of 2. The MAX504’s internal op amp may be configured for a gain of 1 or 2, as well as for unipolar or bipolar output voltages. The MAX504 can also be used as a four-quadrant multiplier without external resistors or op amps. For parallel data inputs, see the MAX503 data sheet. For a hardware and software compatible 12-bit upgrade, refer to the MAX531/MAX538/MAX539 data sheet.

» Audio Systems
» Battery-Operated/Remote Industrial Controls
» Battery-Powered Test Instruments
» Digital Gain and Offset Control
» Machine- and Motion-Control Devices

Transistors

A transistor is a semiconductor device, commonly used as an amplifier or an electrically controlled switch. The transistor is the fundamental building block of the circuitry that governs the operation of computers, cellular phones, and all other modern electronics.

Because of its fast response and accuracy, the transistor may be used in a wide variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillators. Transistors may be packaged individually or as part of an integrated circuit, which may hold a billion or more transistors in a very small area.
Introduction
Modern transistors are divided into two main categories: bipolar junction transistors (BJTs) and field effect transistors (FETs). Application of current in BJTs and voltage in FETs between the input and common terminals increases the conductivity between the common and output terminals, thereby controlling current flow between them. The transistor characteristics depend on their type. See Transistor models.
The term "transistor" originally referred to the point contact type, but these only saw very limited commercial application, being replaced by the much more practical bipolar junction types in the early 1950s. Today's most widely used schematic symbol, like the term "transistor", originally referred to these long-obsolete devices.[1] For a short time in the early 1960s, some manufacturers and publishers of electronics magazines started to replace these with symbols that more accurately depicted the different construction of the bipolar transistor, but this idea was soon abandoned.
