Datasheet	APM80900-Allegro.pdf

The APM80900 is a complete synchronous buck switching regulator module that provides constant current output to drive high-power LEDs.

It integrates both high-side and low-side N-channel switches, inductor, high frequency VIN and boot capacitors.

A true average current is output using a cycle-bycycle, controlled on-time method.

Automotive AEC-Q100 qualified.
Supply voltage 4.5 to 36 V, maximum 40 V.
Complete 1.5 A maximum output compact LED driver.
Integrated inductor, VIN, and boot capacitors.
Ultra-low EMI architecture, fSW > 2 MHz.
Spread spectrum for improved EMC.
Integrated high-side and low-side MOSFETs: 80 mΩ / 60 mΩTYP , 90% efficiency at 1 A.
5 V, 14 mA LDO regulator for peripheral circuits.
Dimming via external PWM or EN pin.
