UCD3138FW-HSFB

UCD3138 Hard Switched Full Bridge (HSFB) topology firmware gets a designer through evaluation to production in power supply designs based on high power Hard Switched Full Bridge topology by providing all-inclusive firmware with input voltage feed forward, copper trace current sensing, on the fly dead time and switching frequency adjustment and startup into pre-bias.

This firmware comes with native support for following features:

• Excellent voltage regulation and line regulation
• Input voltage feedforward
• Output voltage soft start with pre-bias
• Load current sharing
• Copper trace current sensing with temperature compensation
• Oversampling Function for Enhanced Transient response
• Fully programmable dead-time for efficiency optimization
• Constant power/constant current overload protection
• Cycle-by-cycle current limiting
• Short-circuit protection with automatic re-start
• PMBus1.2 (400 KHz) for telemetry

 What’s Included:

• Application demo code
• EVM and firmware documentation
