UCD3138FW-PSFB

UCD3138 Phase Shift Full Bridge quickly gets a designer through evaluation to production in power supply designs based on high power PSFB topology by providing all-inclusive firmware with peak current mode control support, adaptive dead time optimization and programmable slope compensation.

This firmware comes with native support for following features:

• Peak current mode control w/ internal slope compensation & programming blanking time
• Excellent voltage regulation and line regulation
• Non-linear control for enhanced transient response oversampling function for enhanced transient response
• Adaptive dead-time for optimizing efficiency
• Constant power/constant current control
• Cycle-by-cycle current limiting
• Short-circuit protection with automatic re-start
• Load current sharing
• SR control and burst mode to improve light load efficiency
• Faults protections such as OCP, OVP, OTP
• PMBus1.2 (400 KHz) for configuration and telemetry functions

 What’s Included:

• Application examples
• EVM and firmware collaterals
