Description

General part information

MAX17633 Series

The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power supply solutions. The MAX17633 is a high-efficiency, high-voltage, Himalaya 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 pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuous-conduction mode (DCM) to enable high efficiency under full-load and light-load conditions.The feedback-voltage-regulation accuracy over -40°C to +125°C for the MAX17633A, MAX17633B, and MAX17633C is ±1.3%. Simulation models are available.ApplicationsBase-Station Power SuppliesDistributed Supply RegulationGeneral-Purpose Point-of-LoadHigh-Voltage Single-Board SystemsIndustrial Control Power SuppliesWall Transformer Regulation
