DESCRIPTION
– Margining Up/Down with 2-mV Step
The TPS40422 is a dual-output PMBus synchronous
– Programmable Fault Limit and Response
buck controller. It can be configured also for a single,
– Output Voltage, Output Current Monitoring
two-phase output.
– External Temperature Monitoring with
Its wide input range can support 5-V and 12-V
