GENERAL DESCRIPTION
The MAX5951 PWM section utilizes a voltage-mode control scheme for good noise immunity and offers external compensation, allowing for maximum flexibility with a wide selection of inductor values and capacitor types. The device operates at a fixed switching frequency that is programmable from 100kHz to 1MHz and can be synchronized to an external clock signal though the SYNCIN input. The device includes undervoltage lockout (UVLO) and digital soft-start. Protection features include lossless valley-mode current limit, hiccup-mode output short-circuit protection, and thermal shutdown. The MAX5951 is available in a space-saving 5mm x 5mm, 32-pin thin QFN package and is specified for operation over the -40°C to +85°C extended temperature range. Refer to the MAX5950 data sheet for a pincompatible PWM controller with hot swap. FEATURES
