The T8602 is a power supply IC for LED driver that had a characteristic to operate without electrolytic capacitors which is necessary for the DC power supply structure. The IC has the control circuit built-in one
package. And it is realized miniaturization, low cost by removing electrolytic capacitors. Moreover, it is realized long operating life and high energy efficiency of LED lamp. The T8602 is available in SOT-23 and SOP-8 Lead-free package.
FEATURES
• Supports the universal AC input voltage
• PWM controls the power MOSFET at average oscillator frequency (67kHzTyp), feedback controls that assumed reference voltage (0.3VTyp) a standard to keep a fixed LED output current. Stop operating when a VCC voltage became less than Operating Supply Voltage.
• Over Voltage Protection / Thermal Shut Down（Stop operating by latch mode）
• Adjustable Over Current Protection
• Doing the input voltage monitor level in the 0V neighborhood by intermittent operation and operating repeatedly (In the case of the use to have power factor or dimming function, it is possible by adjustment of the voltage monitor)
• PWM and linear dimming.
Applications
• LED/Display Back Light Driver
• Lightings
• Communication Devices
• Handheld Electronics
