This Synchronous Buck Evaluation Board features Microchip's 1A 1.4MHz synchronous buck regulator in two buck converter applications.
The Texas Instruments TPS62020 evaluation module (EVM) for low-power, high-efficiency, step-down converters helps designers evaluate this device. The EVM enables evaluation of different device modes and device performance.
The TPS64202EVM-023 is an evaluation tool for the TPS64202 inductive step-down controller in SOT-23 package which can supply voltages down to 1.2V from a 1.8-V to 6.5-V input.
The TPS40200EVM-001 evaluation module (EVM) uses the TPS40200 nonsynchronous buck converter to provide a resistor-selected 3.3-V output voltage that delivers up to 2.5 A from a 12-V input bus. The EVM operates from a single supply and uses a single P-channel power FET and Schottky diode to produce a low-cost buck converter. The part operates at a 300-kHz clock frequency with provision for externa…
The Texas Instruments TPS62050 and TPS62052 evaluation modules (EVM) for low-power, high-efficiency, step-down converters help designers evaluate these devices. The EVMs make it possible to evaluate different modes of the devices as well as the device performance.
The controller utilizes a constant on-time control scheme which eliminates the need for external compensation components, allowing the power supply designer to minimize necessary board space and reduce costs.
The demo circuit 1693A is an isolated flyback μModule® DC/DC converter featuring the LTM8047. The demo circuit is designed for a 5V output from a 4.5V to 30V input. The typical current capability of the 5V output varies with input voltage from about 110mA at VIN = 4.5V to about 350mA at VIN = 30V.
The LM5118 evaluation board is designed to provide the design engineer with a fully functional, Emulated Current Mode Control, buck-boost power converter to evaluate the LM5118 controller IC. The evaluation board provides a 12V output with 3A of output current capability. The evaluation board’s wide input voltage range is from 75V to 5V, with operation down to 3V with some component changes. The e…
The LM22670 series of regulators are monolithic integrated circuits which provide all of the active functions for a step-down (buck) switching regulator capable of driving up to 3A loads with excellent line and load regulation characteristics. High efficiency (>90%) is obtained through the use of a low ON-resistance N-channel MOSFET.
This evaluation board is an offline, wide-range, VIPer22A-E dual-output power supply with a switching frequency of 60 kHz and is set up for secondary regulation with an optocoupler. One output delivers 5 V at 1 A and a second output delivers 12 V at 0.42 A, making for a total output power of 10 W.
