MAXIM INTEGRATED / ANALOG DEVICES MAX797ESE DC-DC Controller

The MAX797ESE+ is a high-performance, step-down (buck) DC-DC controller designed for CPU power regulation in portable and battery-powered systems. It features a synchronous rectifier for improved efficiency—up to 96%—and supports output voltages adjustable from 2.5V to 6V, with preset 3.3V and 5V options at up to 10A. The device operates from a supply voltage range of 5V to 30V and functions across a temperature range from -40°C to 85°C. It employs a fixed frequency PWM mode at 150kHz or 300kHz to reduce noise and interference, making it suitable for sensitive mobile applications. Advanced circuitry allows it to handle dynamic CPU loads with quick transient response within five clock cycles. It features a bootstrap circuit for efficient N-channel MOSFET switching, minimizing system cost and crowbar currents. Additional features include a programmable soft start, automatic bootstrap circuitry, multiple regulated outputs, and a maximum power loss of just 8mW at dropout. The device is ideal for power management in portable electronic devices and mobile communication equipment.
