Automotive Off-battery Dual-phase Boost Converter Reference Design
Description
This reference design is a high power: wide input voltage range circuit that uses synchronous boost controllers in a dual-phase configuration outputting four (4) switchable 12-V rails that each can supply up to 2.5 A with diagnostic features; plus a dual synchronous buck that generates two high current: lower voltage rails.
Features
- Wide input voltage range of 9V to 20V: support transient down to 6V and up to 36VDual-phase high current synchronous boost controllers configuration with > 98% efficiency under typical operating conditionsDual high-current synchronous outputs: 5V: 3A nominal; 3.8V: 6.5A nominalReverse battery protection with zero IQ smart diode controllerMinimized AM radio band interference
