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.
