Switching frequency125-2000 kHz
Output 162 V
IC revision1.0

Description

The NCV78902R1DAGEVB is a form factor Reference Design of Automotive 2-phase Booster Controller. The reference design can be interfaced via I/O pins and the SPI bus to an external microcontroller. It can be combined with Buck daughter boards and create evaluation kit which provides a complete solution turning SPI commands into LED string control.

Features

  • Single Chip Two−Phase Booster
  • Current Sensing on Shunt Resistors or MOSFETs’ RDSon
  • Stand−Alone/Limp Home Mode
  • Built−in Programmaable Soft−Start
  • Superior Stability and Response Time
  • Designed for Small Output Capacitor
  • Low EMC Emission
  • High Operating Frequencies to Reduce Inductor Size − up to 2 Mhz
  • SEPIC Mode Supported
  • 4 MHz SPI Interface for Dynamic Control of System Parameters
  • 48 V Battery System Compliant
  • ASIL B Compliant; AEC−Q100 Qualified and PPAP Capable
  • This Device is Pb-Free, Halide Free and are RoHS Compliant

Typical applications

  • High current LEDs
  • Automotive front lighting applications like high beam, low beam, DRL (daytime running light), turn indicator, fog light, static cornering
