Telecommunications Equipment
Startup Sequencing
Power Supply Modules
Adaptive Gate Drive
Remote Sensing (Via Separate GND/PGND)
Internal Gate Drivers for N-channel MOSFETs
The TPS40100 is a mid voltage, wide-input (between
Internal 5-V Regulator
4.5 V and 18 V), synchronous, step-down controller.
24-Pin QFN Package
The TPS40100 offers programmable closed loop
soft-start, programmable UVLO (with programmable
Thermal Shutdown
hysteresis), programmable inductor sensed current
Programmable Overcurrent Protection
limit and can be synchronized to other timebases.
Power Good Indicator
The TPS40100 incorporates MOSFET gate drivers
1%, 690-mV Reference
for external N-channel high-side and synchronous
rectifier (SR) MOSFET. Gate drive logic incorporates
Output Margining, 3% and 5%
adaptive anti-cross conduction circuitry for improved
Programmable UVLO (with Programmable
efficiency, reducing both cross conduction and diode
Hysteresis)
conduction in the rectifier MOSFET. The externally
Frequency Synchronization
programmable current limit provides a hiccup
overcurrent recovery characteristic.
