SLUS719G – MARCH 2007 – REVISED JANUARY 2018 TPS4019x 4.5-V to 18-V Input, 10-Pin, Synchronous Buck Controller With Power Good
1 Features 3 Description TPS40192 and TPS40193 are cost-optimized
synchronous buck controllers that operate from 4.5 V
to 18 V input. These controllers implement a voltagemode control architecture with the switching
frequency fixed at either 600 kHz (TPS40192) or 300
kHz (TPS40193). The higher switching frequency
facilitates the use of smaller inductor and output
capacitors, thereby providing a compact powersupply solution. An adaptive anti-cross conduction
scheme is used to prevent shoot through current in
the power FETs. 1 Input Operating Voltage Range: 4.5 V to 18 V
Up to 20-A Output Currents
Supports Pre-Biased Outputs
