The MAX797CSE is a step-down DC-DC converter 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 at fixed frequencies of 150kHz or 300kHz, with a logic-controlled, synchronizable PWM mode that reduces noise and RF interference, making it suitable for sensitive applications.
The MAX797CSE includes features such as programmable soft-start, automatic bootstrap circuitry for N-channel MOSFETs, and a precision 2.505V reference output. It also has a SKIP override input for automatic switchover to idle-mode operation at light loads or to force fixed-frequency mode for lowest noise.
Packaged in a 16-SOIC surface-mount package, the MAX797CSE is designed for applications including notebook and subnotebook computers, PDAs, mobile communicators, and cellular phones.
The input voltage range is 4.5V to 30V.
The adjustable output voltage range is 2.5V to 6V.
Preset output voltages of 3.3V and 5V are available, at up to 10A.
The maximum efficiency is 96%.
The MAX797CSE supports fixed switching frequencies of 150kHz and 300kHz.
The operating temperature range is 0°C to 70°C.
The MAX797CSE is available in a 16-SOIC package, suitable for surface mounting.
