3 Description

The LM5046 PWM controller contains all of the

features necessary to implement a phase-shifted fullbridge

topology power converter using either current

mode or voltage mode control. This device is

intended to operate on the primary side of an isolated

DC-DC converter with input voltage up to 100 V. This

highly integrated controller-driver provides dual 2-A

high- and low-side gate drivers for the four external bridge MOSFETs, plus control signals for the

secondary-side synchronous rectifier MOSFETs.

External resistors program the dead-time to enable

zero-volt switching of the primary FETs. Intelligent

startup of the synchronous rectifiers allows monotonic

turnon of the power converter even with prebias load

conditions. Additional features include cycle-by-cycle

current limiting, hiccup mode restart, programmable

soft-start, synchronous rectifier soft-start, and a 2-

MHz capable oscillator with synchronization capability

and thermal shutdown.
