UCC28782BDLRTWR General Description

The UCC28782BDLRTWR is a high-performance active-clamp flyback controller designed specifically for USB Type C™ Power Delivery applications. Its innovative design allows for exceptional efficiency levels exceeding 93%, achieved through the recovery of leakage inductance energy and adaptive zero voltage switching (ZVS) technology that adjusts dynamically based on the load conditions

Key Features

Active clamp recovers leakage inductance energy
Adaptive control for fast zero voltage switching (ZVS) tracking and dead time optimization
Integrated switching bias regulator supports USB Type-C PD wide output voltage range with one auxiliary winding
EMI frequency dithering without trade-offs on transient response or audible noise
Dynamic bias power management for digital isolator and GaN driver
Programmable Adaptive Burst Mode (ABM) with internal compensation
Active X-capacitor (X-cap) discharge
Over-temperature, over-voltage, output short-circuit, over-current, over-power, and pin-fault protections
Auto-recovery and group-latch fault options with fast latch-reset capability
4x4-mm 24-pin QFN package
