Please check latest availability status for a specific part variant.

Description

The MAX17530 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4V to 42V input. The converter can deliver up to 25mA and generates output voltages from 0.8V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.75% over -40°C to +125°C.

The MAX17530 uses peak-current-mode control and can be operated in pulse-width modulation (PWM) or pulse-frequency modulation (PFM) modes.

The device is available in a 10-pin (3mm x 2mm) TDFN and 10-pin (3mm x 3mm) µMAX® packages. Simulation models are available.
