MAX17502GATB+

60V, 1A, Ultra-Small, High-Efficiency,  Synchronous Step-Down DC-DC Converter

开关稳压器 60V 1A 600kHz Synch Step-Down Regulator

General Description  

The MAX17502GATB+ MAX17502 high-efficiency, high-voltage, synchronous  step-down DC-DC converter with integrated MOSFETs  operates over a 4.5V to 60V input voltage range. This  device is offered in a fixed 3.3V , 5V or adjustable output  voltage (0.9V to 92%VIN) while delivering up to 1A of  current. The output voltage is accurate to within ±1.7%  over -40°C to +125°C. The MAX17502 is available in  compact TDFN and TSSOP packages. Simulation models  are available.
