45V Synchronous Rectification Half Bridge LED Drive Controller [SS8102]

SS8102 is a high -efficiency, constant current, low -voltage -type synchronous half -bridge DC/DC converterDriver chip, Can drive a current load of up to 25A, have PWM lighting resolution with more than 100K: 1, and adopt advanced stagnant constant interrupt time control technology. There is no need for load compensation, and fast load instantaneous response and other characteristics.

Product Description:

SS8102 supports synchronous rectification and asynchronous rectificationCircuitTopology, flexible design, can choose the appropriate architecture as needed; it has good linearity and stable constant current characteristics, which can be accurately dimmed and working stably under bad power supply conditions. The external output current can be connected by external output current.resistance(RCS) Adjustment can also be achieved by adjusting the voltage on the IADJ of the simulated lighting control pin; the current capacity can reach 25A.

Features:

■ Maximum output 25A driver current

■ 100K: 1 High PWM Lighting Resolution

■ Simulation lighting ratio 250: 1  

■ Input voltage range: 8V ~ 45V  

■ The frequency of the switching power supply can be adjusted

■ Packaging: ETSSOP16 & Nbsp;

■ Good lighting and micro -adjustment

■ Stable constant current characteristics

■ Protection characteristics

-VCC under pressure lock

-The Overcurrent Protection

-The overheating protection

-Outage of output arrears pressure protection

-LED opening protection

The chip enters the PWM signal through the DIM tube foot to flexibly implement the lighting control of LEDs. At the same time, it supports PWM and linear dimming. It can perform independent lighting current control, optimize the low -gray lighting characteristics, avoid jittering and flashing problems.LED provides better linear lighting characteristics.

In addition, the SS8102 provides a series of protection functions, including under pressure locking (UVLO), overheating protection (OTP), LED opening and short -circuit protection, and output arrears of protection; packaging with heat dissipation tablets is still outdated when large currents pass.Can run stably.

SS8102 high -efficiency, high -performance LED driver solution, optimizing the dimension of the dimming, and comprehensive protection function, providing excellent performance and reliability for LED lighting control requirements.
