The LM3100 Synchronously Rectified Buck Converter features all functions needed to implement a highly efficient, cost effective buck regulator capable of supplying 1.5A to loads with voltages as low as 0.8V. Dual 40V N-Channel synchronous MOSFET switches allow for low external component thus reducing complexity and minimizing board space. The LM3100 is designed to work exceptionally well with cer…

This application note describes the characteristics and features of a 150 W SMPS demonstration board (EVL150W-ADP-SR), tailored to all-in-one computer power supply (PS) specifications.

This board is designed as a discontinuous flyback regulator delivering 0.5A at 12V. The AC input is rectified and filtered by the bridge BR1, the bulk capacitor C1, and C2 to generate the high voltage DC bus applied to the primary winding (pins 8-10) of the transformer, TR1.

The Texas Instruments low-power dc-dc EVMs for high-efficiency step-down converters, TPS62000 to TPS62007, help designers evaluate these devices. The EVMs make it possible to evaluate different modes of the devices as well as the device performance.

This note describes the performances of a 90 W, wide-range mains, power-factor-corrected AC-DC adapter reference board. Its electrical specification is tailored on a typical hi-end portable computer power adapter. The peculiarities of this design are the very low no-load input consumption (

The EVM features a TPS84x10 synchronous buck IPS device configured for operation with typical 3.3-V and 5-V input bus applications. The output voltage can be set to one of five popular values by using a simple configuration jumper. In similar fashion, the switching frequency can be set to one of four values by use of a jumper.

The TPS8267x device is a complete 600mA, DC/DC step-down power supply intended for low-power applications. Included in the package are the switching regulator, inductor and input/output capacitors. No additional components are required to finish the design.

The LMZ14203EXT/2EXT/1EXT SIMPLE SWITCHER® power modules are easy-to-use DC-DC solution capable of driving up to a 1A, 2A, or 3A load, respectively, with exceptional power conversion efficiency, output voltage accuracy, line and load regulation. They are available in an innovative package that enhances thermal performance and allows for hand or machine soldering.

Demonstration circuit 1379A demo board featuring the LTM®8025 µModule® is designed to deliver a 3.3V output from a 5.5V to 36V input. The wide input range of the LTM8025 allows a variety of input sources such as automotive batteries, wall adaptors and industrial supplies.

Demonstration circuit DC1400A features the LTM®4608AEV, the high efficiency, high density switch mode step-down power module. The input voltage range is 2.5V to 5.5V. The output voltage is jumper selectable from 0.6V to 3.3V. The rated load current is 8A although derating is necessary for certain VIN, VOUT and thermal conditions.
