FEATURES  
DESCRIPTION  
2
Secondary-Side Controller Optimized for 5-V  
This  
GREEN  
Rectifier™  
controller  
is  
a
Systems  
high-performance controller and driver for standard  
and logic-level N-channel MOSFET power devices  
used for low-voltage secondary-side synchronous  
rectification.  
Up to 600-kHz Operating Frequency  
VDS MOSFET-Sensing  
1.6-Ω Sink, 2.0-Ω Source Gate-Drive  
Impedances  
The combination of controller and MOSFET emulates  
a near-ideal diode rectifier. This solution not only  
directly reduces power dissipation of the rectifier but  
also indirectly reduces primary-side losses as well,  
due to compounding of efficiency gains.  
Micro-Power Sleep Current for 90+ Designs  
Automatic Light-Load Management  
Synchronous Wake-Up From Sleep and  
Light-Load Modes  
Using  
drain-to-source  
voltage  
sensing,  
the  
UCC24610 is ideal for Flyback and LLC-resonant  
power supplies but can also be used with other power  
architectures. The UCC24610 is optimized for output  
voltages from 4.5 V to 5.5 V, and is suitable for use  
with lower and higher output voltages as well.  
Protection Features on Programming Inputs  
SYNC Input for CCM Operation  
20-ns Typical Turn-Off Propagation Delay  
Improved Efficiency and Design Flexibility  
Over Traditional Diode Solution  
The  
UCC24610  
offers  
a
programmable  
May Be Biased Directly From 5-V Output  
Minimal Component Count  
false-triggering filter,  
a
programmable timer to  
automatically switch to Light-Load Mode at light load,  
and a SYNC input for optional use in Continuous  
Conduction Mode (CCM) systems. Protection  
features on TON and EN/TOFF pins prevent  
run-away on-time due to open-circuit or short-circuit  
fault conditions.  
APPLICATIONS  
AC/DC 5-V Adapters  
5-V Bias Supplies  
Low Voltage Rectification Circuits  
Flyback and LLC Converters  
This device is available in an 8-pin SOIC package  
and an 8-pin, 3-mm x 3-mm QFN package with  
PowerPad™.
