Allegro Microsystems A80803 | Demoboard APEK80803KET-TS

Description

The A80803 Evaluation Board (EVB) is designed to aid system designers with the evaluation of the operation and performanceof the A80803, a multi-topology, fixed frequency, switch-mode DC/DC controller for LED lighting applications with built-in support for low/high-beam operation and remote configuration via SPI.The A80803 EVB is available in four configurations to support low/high-beam and fixed LED string applications. The EVB arrives configured to operate in one of four modes and has a mark on one of the silkscreen boxes in the top right of the EVB to identify in which mode the EVB is configured.

Features

• Multi-topology controller, including changeover during high/low beam, provides flexibility in number of LEDs driven
• Unique slew rate control solves over/undershoot issues during high/low intensity transition
• Options for SPI control or EEPROM programming enable a choice of local uC interface or "standalone" cost optimized solution
• Includes a local 5V/50mA linear regulator for low power uC or external circuitry
• Incorporates extensive fault detection and reporting through SPI, or hardwired fault signals, for globally recognized safety compliance
• Wide input and output voltage covers a broad range of use cases

Typical applications

• Automotive Lighting
