1 / 43 page  1. Introduction The ASL4501SHN is a highly integrated and flexible four-phase DC-to-DC boost converter IC. It has a serial peripheral interface (SPI) allowing control and diagnostic communication with an external microcontroller. It is designed primarily for use in automotive LED lighting applications and provides an optimized supply voltage for ASLx41xSHN multichannel LED buck driver. 2. General description The ASL4501SHN 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 via SPI for output voltages of up to 80 V, to power the LED buck driver IC. The ASL4501SHN is a four-phase converter which can have two independent outputs. The driver has the flexibility to be configured, via the SPI, as a single output converter, or with multiple combinations of number of outputs and phases. The ASL4501SHN boost converter can drive up to four external low-side N channel metal-oxide-semiconductor field-effect transistors (MOSFETs) from an internally regulated adjustable supply. It can be used to drive either logic or standard level MOSFETs. The integrated SPI also allows for programming the supply under/overvoltage range, output voltage range and DC-to-DC switching frequency. It enables the optimization of external components and flexibility for electromagnetic compatibility (EMC) design. This interface can also be used to provide diagnostic information such as the driver temperature. Additional features include protection against load dump transient voltages of up to 60 V and thermal shutdown when the junction temperature of the ASL4501SHN exceeds +175 C. The device is housed in a very small HVQFN32 pin package and is designed to meet the stringent requirements of automotive applications. It is fully AEC-Q100 grade 1 qualified. It operates over the 40 C to +125 C ambient automotive temperature range. ASL4501SHN Four-phase boost converter Rev. 2 — 10 January 2018 Product data sheet |
