MAX17550/51 Synchronous Step-Down DC-DC Converters

Maxim's MAX17550/51 High-Efficiency Synchronous Step-Down DC-DC Converters come with integrated MOSFETs that operate over a 4V to 60V input voltage range. These converters can deliver 25mA or 50mA and generates output voltages from 0.8V up to 0.9 x V_IN. The feedback (FB) voltage is accurate to within ±1.75% over -40°C to +125°C. The MAX17550/51 uses peak-current-mode control. The device 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.
