The MAX797CSE is a versatile DC-DC switching controller designed for battery-powered systems, providing main CPU power. It achieves up to 96% efficiency through synchronous rectification and Maxim's proprietary Idle Mode™ control scheme, extending battery life.
This controller supports a wide input voltage range of 4.5V to 30V and offers an adjustable output voltage from 2.5V to 6V, with preset 3.3V and 5V outputs available at up to 10A. It operates with fixed-frequency PWM at either 150kHz or 300kHz, featuring logic-controlled and synchronizable modes for reduced noise and RF interference, making it suitable for sensitive applications.
The MAX797CSE includes features like programmable soft-start, automatic bootstrap circuitry for N-channel MOSFETs, and a SKIP override input for automatic switchover to idle-mode at light loads or fixed-frequency mode for lowest noise. It is housed in a 16-SOIC package, suitable for surface mounting.
Key applications include notebook and subnotebook computers, PDAs, mobile communicators, and cellular phones, where efficient and reliable power conversion is critical.
