UCC28730 Zero-Power Standby PSR Flyback Controller

with CVCC and Wake-Up Monitoring

1 Features

3 Description

The UCC28730 isolated-flyback power supply

controller provides Constant-Voltage (CV) and

Constant-Current (CC) output regulation without the

use of an optical coupler, and wake-up signal

detection to improve transient response to large load

steps. A minimum switching frequency of 30 Hz

facilitates achieving less than 5 mW of no-load

power. This device processes information from the

primary power switch and an auxiliary flyback winding

for precise control of output voltage and current. The

wake-up monitoring works with a secondary-side

alarm device such as the UCC24650 to deliver rapid

response to heavy load steps using minimal output

capacitance.

•

Resonant-Ring Valley-Switching Operation for

Highest Overall Efficiency

An internal 700-V start-up switch, dynamically-

controlled operating states and a tailored modulation

profile support ultra-low stand-by power without

sacrificing start-up time or output transient response.

Control algorithms in the UCC28730 allow operating

efficiencies to meet or exceed applicable standards.

Discontinuous conduction mode (DCM) operation

with valley-switching reduces switching losses.

Modulation of the switching frequency and primary

current peak amplitude (FM and AM) keeps the

conversion efficiency high across the entire load and

line ranges.
