About This Product

■Primary side regulated dimming LED driver with active PFC

HT7L5502/03 is a controller for implementing constant current LED drivers with power factor correction (PFC) functionality. Using primary-side regulation, accurately control LED output current without the need for secondary-side feedback components. HT7L5502/03 operates in quasi-resonant mode to achieve higher efficiency. Output current can be adjusted via the DIM pin. The HT7L5502/03 integrates robust protection features such as output overvoltage protection, output short circuit protection (SCP), VCC overvoltage protection, VCC undervoltage lockout, and overtemperature protection (OTP).

■Features

・Primary side current control without secondary side feedback circuit ・Power factor is 0.9 or more

■Supports wide dimming range

・PWM dimming range: 5%~100% ・Analog dimming range: 10%~100% ・Strict LED constant current control of ±3% ・Line correction to improve LED current accuracy ・Constant voltage control when LED is off

■Complete protection functions to increase safety

・Output overvoltage protection ・Output short circuit protection ・VCC overvoltage protection ・VCC low voltage lockout ・External/internal overheat protection ・Package type: 8 pin SOP
