ASL1507SHN - Single-phase and two-phase boost converter
The ASL1507SHN; ASL2507SHN has a fixed frequency peak current mode control with parabolic/non‑linear slope compensation.
It can operate with input voltages from 5.5 V to 40 V.
It can be configured in boost topology via SPI for output voltages of up to 80 V, to power the LED buck driver IC.

ASL1507SHN; ASL2507SHN Single-phase and two-phase boost converter with limp-home mode Rev.
1 26 April 2018 Product data sheet 1 Introduction The ASL1507SHN is a highly integrated and flexible one-phase DC-to-DC boost converter IC.
The IC has one integrated gate driver which can drive one external power metal-oxide-semiconductor field-effect transistor (MOSFET) and two integrated proportional-integral (PI) controllers which can regulate the output voltage.
It has a serial peripheral
