The MAX17542G high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over 4.5V to 42V input. The converter can deliver up to 1A and generates output voltages from 0.9V up to 0.92 x VIN. The feedback (FB) voltage is accurate to within ±1.7% over -40°C to +125°C.
The MAX17542G uses peak-current-mode control with pulse-width modulation (PWM) and operates with fixed 600kHz switching frequency at any load. The device is available in a 10-pin (3mm x 2mm) TDFN package. Simulation models are available.
Applications
- Base Station, VOIP, Telecom
- Battery-Powered Equipment
- General-Purpose Point of Load
- Home Theatre
- HVAC and Building Control
- Industrial Process Control
