ASL1507SHN
description
The ASL1507SHN; ASL2507SHN has a fixed frequency peak current mode control with parabolic/non‑linear slope pensation. 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 munication 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...
