Introduction

PC1226 is a synchronous buck driver control chip used to drive high-power LEDs. The chip has an operating voltage range of 7~60V, can stably output a driving current of up to tens of amperes, and has extremely high conversion efficiency.

PC1226 integrates a PMOS driver module to drive the high-side PMOS power MOS, and forms a synchronous buck structure with the low-side NMOS, thereby realizing a synchronous buck loop. The external power tube can achieve a driving power of up to 100W or more. The chip uses high-side current detection technology to accurately control the output current by detecting the voltage across the resistor; high-side current detection avoids ground interference and improves system stability. PC1226 can use PWM dimming, and the dimming effect is excellent. PC1226 uses MSOP10-PP package, small size
