General Description

The BD18397/98RUV-M are 2 ch/3 ch synchronous buck

DC/DC LED drivers with using on-time topology

supporting near fixed switching frequency and fast

switching duty regulation and with using average LED

current feed buck topology for more accreted LED current

regulation system over wide input, LED output range.

The BD18397/98RUV-M can support individual 10-bit

analog dimming and 10-bit PWM dimming for LED current

by programing the 10-bit register via SPI.

The BD18397/98RUV-M will support LIMP-HOME mode,

if SPI communication has an error. In the LIMP-HOME

mode, individual LED current can be set by the external

pins and can keep LED current sourcing during applying

input power without SPI communication.

Features

◼ AEC-Q100 Qualified(Note 1)

◼ ISO 26262 Process Compliant to Support ASIL-B

◼ On-time Topology for Near Fixed Frequency Switching

◼ Protection Diodes Less for Current Sense Pins

◼ Cycle-by-cycle Switch Over Current Protection

◼ Thermal Shutdown (TSD)

◼ Thermal Sensor Reading

◼ Serial Peripheral Interface (SPI)

◼ LIMP-HOME Mode
