概述

说明

The MAX77533 is a synchronous 1.5A step-down DC-DC converter optimized for portable 2-cell and 3-cell battery-operated and USB-C applications. The converter operates on an input supply between 3V and 14V. Output voltage is adjustable between 0.8V and 5V in 50mV steps through an I2C serial interface or 1.55V to 99% of the supply voltage with external feedback resistors. Factory-programmed default voltages of 1.2V, 1.8V, and 3.3V are offered to reduce component count for common rails. The device features a low-IQ SKIP mode which allows excellent efficiency at light loads.

Dedicated enable and power-OK (POK) pins allow simple hardware control. An I2C serial interface is optionally used for full configuration and control for dynamic voltage scaling and system power optimization.

Built-in undervoltage lockout (UVLO), output active discharge, cycle-by-cycle current limit, thermal shutdown, and short-circuit protection ensure safe operation under abnormal operating conditions.

The MAX77533 is available in a 12-bump, 0.4mm pitch wafer-level package (WLP).
