detailed description
low-side driver
The low-side driver is designed to drive low Rds(on) N-channel MOSFETs. The current rating of the driver is
2 A, source and sink.
high-side driver
The high-side driver is designed to drive low Rds(on) N-channel MOSFETs. The current rating of the driver is
2 A, source and sink. The high-side driver can be configured as a GND-reference driver or as a floating bootstrap
driver. The internal bootstrap diode is a Schottky, for improved drive efficiency. The maximum voltage that can
be applied from BOOT to ground is 30 V.
deadtime (DT) control
Deadtime control prevents shoot through current from flowing through the main power FETs during switching
transitions by controlling the turn-on times of the MOSFET drivers. The high-side driver is not allowed to turn
on until the gate drive voltage to the low-side FET is low, and the low-side driver is not allowed to turn on until
the voltage at the junction of the power FETs (Vdrn) is low; the DT terminal connects to the junction of the power
FETs.
ENABLE
The ENABLE terminal enables the drivers. When enable is low, the output drivers are low.
IN
The IN terminal is the input control signal for the drivers. The TPS2830 has a noninverting input; the TPS2831
has an inverting input.
SYNC
The SYNC terminal controls whether the drivers operate in synchronous or nonsynchronous mode. In
synchronous mode, the low-side FET is operated as a synchronous rectifier. In nonsynchronous mode, the
low-side FET is always off.
CROWBAR
The CROWBAR terminal overrides the normal operation of the driver. When the CROWBAR terminal is low,
the low-side FET turns on to act as a clamp, protecting the output voltage of the dc/dc converter against over
voltages due to a short across the high-side FET. V
IN
should be fused to protect the low-side FET.
High-level input voltages on ENABLE, SYNC, CROWBAR, IN, and DT must be greater than or equal to VCC.
