45ohm low Rds(on)  Full protection: Thermal/Start-Up/LED Open-/Short- Circuit  Only 4 external components required  Package MSL Level : 3 MBI6652 Step-Down LED Driver Small Outline Transistor GST: SOT-23-6L Mini Small Outline Package GMS: MSOP-8L-118mil Product Description The MBI6652 is a high efficiency, constant current and step-down DC/DC converter.
It is designed to deliver constant current to light up high power LED with only 4 external components.
With hysteretic PFM control scheme, MBI6652 improves the efficiency of light loading.
The output current of MBI6652 can be programmed by an external resistor and LED dimming can be controlled via pulse width modulation (PWM) through DIM pin.
In addition, the start-up fun...
