DESCRIPTION
JW®1251O is a controller for driving externalNMOSFET to remove the 100/120Hz LED currentripple on AC/DC power by a capacitor betweenvC and GND.
The adaptive technology of JW12510 ensuresminimum power dissipation on NMOSFET whileremoving LED current ripple.
Patented control strategies are optimized fordimmable solutions.
JW12510enablesgoodrippleremovingperformance in the whole output current rangeand excellent system dynamic responding speedin the fast dimming.
JW12510 provides short circuit protection andover temperature protection (OTP). OTP istrigged at 145°C,ripple current will be releasedwith the temperature.
FEATURES
• Controller for adaptive 100/120Hz currentripple remover
• Built-in zener diode for input voltageclamping
• Compatible with dimmable applications
• Programmable amplitude of LED currentripple
• Programmable maximum cathode voltage ofLED
• Programmable maximum LED currentShort protection
• Over temperature protection
• SOT23-6 Package
APPLICATIONS
• LED Lighting
