EVALUATION KIT AVAILABLE
4.5V to 36V, 2A, High-Efficiency, Synchronous Step-Down DC-DC Converter
General Description
The MAX17632 family of parts (MAX17632A, MAX17632B and MAX17632C) is a high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operating over an input-voltage range of 4.5V to 36V. It can delivĀer up to 2A current. The MAX17632A and MAX17632B are fixed 3.3V and fixed 5V output parts, respectively. The MAX17632C is an adjustable output voltage (0.9V to 90% of VIN) part. Built-in compensation across the output-voltage range eliminates the need for external compensation components.
The MAX17632 features peak-current-mode control architecture. The device can be operated in the forced pulsewidth modulation (PWM), or pulse-frequency modulation (PFM), or discontinuous-conduction mode (DCM) to enable high efficiency under full-load and light-load conditions. The MAX17632 offers a low minimum on time that allows high switching freq.
