The MAX17633 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 deliver up to 3.5A current. The MAX17633 is available in three variants MAX17633A, MAX17633B, and MAX17633C. The MAX17633A and MAX17633B are the fixed 3.3V and fixed 5V output voltage parts, respectively. MAX17633C is an adjustable output voltage (from 0.9V up to 90% of VIN) part. Built-in compensation across the output voltage range eliminates the need for external components.
The MAX17633 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 MAX17633 offers a low minimum on-time that allows high switching frequencies and a smaller solution size.
The feedback-voltage-regulation accuracy over -40°C to +125°C for the MAX17633A, MAX17633B, and MAX17633C is ±1.3%.The device is available in a compact 20-pin (4mm × 4mm) TQFN package. Simulation models are available.
