Phase-Shifted Full-Bridge PWM Controller Module – LM5046 Breakout Board
This is a Phase-Shifted Full-Bridge PWM LM5046 carrier board that contains all of the features necessary to implement a phase-shifted full-bridge topology power converter. All inputs and outputs pins are accessible using the header connector. High efficiency DC-DC converter can be created using LM5046 carrier board + External H-Bridge and Transformer. Refer to the datasheet of LM5046 and schematic to configure the frequency, current feedback, delays, etc.
Features

- Under Voltage Lockout UVLO (34V/32V ON/OFF)
- Frequency Of Operations 420Khz (Programmable up to 2Mhz- Set Resistor R10)
- Highest Integration Controller for Small
- Form Factor, High-Density Power Converters
- High-Voltage Start-Up Regulator
- Intelligent Sync Rectifier Start-Up Allows
- Linear Turn-on into Pre-biased Loads
- Synchronous Rectifiers Disabled in UVLO Mode and Hiccup Mode
- Two Independent, Programmable Dead-Time
- Adjustments to Enable Zero-Volt Switching
- Four High-Current 2-A Bridge-Gate Drivers
- Wide-Bandwidth Opto-Coupler Interface
- Configurable for Either Current-Mode or Voltage Mode Control
- Dual-Mode Overcurrent Protection
- Resistor Programmed 2-MHz Oscillator
- Programmable Line UVLO and OVP
