FEATURES  
DESCRIPTION  
The UCC28700 family of flyback power supply  
controllers provides 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. Low start-up current,  
dynamically-controlled operating states and a tailored  
modulation profile support very low stand-by power  
without sacrificing start-up time or output transient  
response.  
< 30-mW No-Load Power for 5-Star Rating  
Primary-Side Regulation (PSR) Eliminates  
Opto-Coupler  
±5% Voltage and Current Regulation  
130-kHz Maximum Switching Frequency  
Enables High-Power Density Charger Designs  
Quasi-Resonant Valley-Switching Operation  
for Highest Overall Efficiency  
Patent-Pending Frequency-Jitter Scheme to  
Ease EMI Compliance  
Control algorithms in the UCC28700 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.  
Wide VDD Range Allows Small Bias Capacitor  
Clamped Gate-Drive Output for MOSFET  
Protection Functions: Over-Voltage, Low-Line,  
and Over-Current  
Programmable Cable Compensation  
(UCC28700 only)  
NTC Resistor Interface (UCC28701, UCC28702  
and UCC28703 only) with Fixed Cable  
Compensation Options  
The controllers have a maximum switching frequency  
of 130 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 UCC28700 allows the level of  
cable compensation to be programmed. The  
UCC28701, UCC28702 and UCC28703 devices allow  
SOT23-6 Package  
APPLICATIONS  
USB-Compliant Adapters and Chargers for  
Consumer Electronics (cell phones, tablets  
and cameras)  
remote temperature sensing using  
a
Negative  
Temperature Coefficient (NTC) resistor while  
providing fixed cable-compensation levels.
