General Description
The MAX5038A/MAX5041A dual-phase, PWM controllers provide high-output-current capability in a compact package with a minimum number of external components. The MAX5038A/MAX5041A utilize a dual-phase, average-current-mode control that enables optimal use of low RDS(ON) MOSFETs, eliminating the need for external heatsinks even when delivering high output currents.

Features
