DESCRIPTION

The UCC28710 family of flyback power supply

controllers provides isolated-output Constant-Voltage

(CV) and Constant-Current (CC) output regulation

without the use of an optical coupler. The devices

process information from the primary power switch

and an auxiliary flyback winding for precise control of

output voltage and current.

Protection Functions

•

Programmable Cable Compensation

(UCC28710, UCC28714 and UCC28715)

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

controlled operating states and a tailored modulation

profile support ultra-low standby power without

sacrificing start-up time or output transient response.

NTC Resistor Interface (UCC28711, UCC28712

and UCC28713) with Fixed Cable

Compensation Options

Control algorithms in the UCC28710 family allow

operating efficiencies to meet or exceed applicable

standards. The output drive interfaces to a MOSFET

power switch. Discontinuous conduction mode (DCM)

with valley switching reduces switching losses.

Modulation of switching frequency and primary

current peak amplitude (FM and AM) keeps the

conversion efficiency high across the entire load and

line ranges.

The controllers have a maximum switching frequency

of 100 kHz and always maintain control of the peak-

primary current in the transformer. Protection features

help keep primary and secondary component

stresses in check. The UCC28710, UCC28714 and

UCC28715 allow the cable compensation to be

programmed. The UCC28711, UCC28712 and

UCC28713 devices allow remote temperature

sensing using a negative temperature coefficient

(NTC) resistor while providing fixed cable-

compensation levels.
