The MAX77503AEWC+ is a synchronous 1.5A step-down DC-DC converter designed for portable battery-operated and USB-C applications. It accepts an input supply voltage ranging from 3V to 14V.
The output voltage is adjustable, offering flexibility for various power requirements. It can be programmed via an I2C serial interface in 50mV steps between 0.8V and 5V, or set using external feedback resistors for a range of 1.55V to 99% of the supply voltage. Factory-preset options for common rails include 1.2V, 1.8V, and 3.3V.
This converter features a 1MHz fixed-frequency switching rate and includes protection features such as undervoltage lockout (UVLO), output active discharge, cycle-by-cycle current limit, and thermal shutdown for safe operation. It is available in a compact 12-bump, 0.4mm pitch wafer-level package (WLP), measuring 1.85mm x 1.4mm with a maximum height of 0.7mm, making it suitable for space-constrained designs.
Applications include high power density supplies for 2-cell/3-cell batteries, portable Li+/Li-ion battery powered devices, drones, HD cameras, and notebook computers.
