General Description

Key Specifications

BD18353EFV-M/MUF-M is a 1ch LED Controller. High

◼ Input Voltage Range:

◼ Maximum Output Voltage:

5 V to 65 V

65 V

side current detection amplifier is built-in.

PWM

dimming duty can be freely set with built-in PWM

generation circuit. PWM dimming realizes by driving an

external P-ch MOSFET. Outputs abnormal LED status

to the FAULT_B pin. Two systems of analog dimming

are built-in. High precision 3.0 V output power supply

for analog dimming and PWM dimming setting is built-in.
