SLUS930D – APRIL 2011 – REVISED NOVEMBER 2016 TPS40400 3-V to 20-V PMBus Synchronous Buck Controller
1 Features 3 Description The TPS40400 is a cost-optimized flexible
synchronous buck controller that operates from a
nominal 3-V to 20-V supply. This controller is an
analog PWM controller that allows programming and
monitoring through the PMBusв„ў interface. Flexible
features found on this device include programmable
soft-start time, programmable short circuit limit, and
programmable undervoltage lockout (UVLO). 1 Input Operating Voltage Range: 3 V to 20 V
