Product details
DESCRIPTION
JW®1251A, integrated with 60V NMOSFET, is used to drive a LED string, and remove the 100/120Hz LED current ripple on AC/DC power by a capacitor between VC and GND.
The adaptive technology of JW1251A ensures minimum power dissipation on NMOSFET while removing LED current ripple.
Patented control strategies are optimized for dimmable solutions.
JW1251A enables good ripple removing performance in the whole output current range and excellent system dynamic responding speed in the fast dimming.
JW1251A provides short circuit protection and over temperature protection (OTP). OTP is trigged at 145ºC, ripple current will be released with the temperature.
FEATURES
• Adaptive 100/120Hz current ripple remover
