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 interface (SPI) allowing control and diagnostic communication with an external
microcontroller.
The ASL2507SHN is a highly integrated and flexible two-phase DC-to-DC boost
converter IC. The IC has two integrated gate drivers which can drive two external power
metal-oxide-semiconductor field-effect transistors (MOSFETs) and two integrated
proportional-integral (PI) controllers which can regulate the output voltage on both
channels. It has a serial peripheral interface (SPI) allowing control and diagnostic
communication with an external microcontroller.
The ASL1507SHN; ASL2507SHN is designed primarily for use in automotive LED
lighting applications and provides an optimized supply voltage for ASLx416/17SHN
multichannel LED buck driver.
For simplicity, the data sheet states always 'gate drivers' and 'output voltages'. The
ASL1507SHN has only one gate driver and can only drive one output.

General description
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.
The ASL1507SHN is a single-phase boost converter with one output voltage. The
ASL2507SHN is a two-phase boost converter, which can have two independent outputs.
The ASL2507SHN is configurable via the SPI interface, as a single output converter with
either one phase or two phases, or two independent output voltages. In case the SPI
communication is lost in an abnormal situation, it switches to limp-home mode operation
ensuring system safety.
The ASL1507SHN; ASL2507SHN boost converter can drive up to two external low-side
N channel MOSFETs from an internally regulated adjustable supply. It can drive either
logic or standard level MOSFETs.
The integrated SPI interface also allows for programming the supply under/overvoltage
range, output voltage range, frequency spread spectrum, and DC-to-DC switching
frequency. It enables the optimization of external components and flexibility for
electromagnetic compatibility (EMC) design. This interface can be used also to provide
diagnostic information such as the device temperature, battery voltage, VGG voltage,
output voltage etc.
