MAX17502GATB+T
60V, 1A, Ultra-Small, High-Efficiency, Synchronous Step-Down DC-DC Converter
开关稳压器 60V 1A 600kHz Synch Step-Down Regulator
MAX17502GATB+T General Description
The 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.
