DESCRIPTION
NAME
NO.
RT_CLK
1
I
Resistor timing and external clock for buck regulator. Resistor should connect to GND (PowerPAD™)
with very short trace to reduce the potential clock jitter due to noise.
COMP
2
O
Buck error amplifier output and input to the output switch current comparator.
VSENSE
3
I
Buck output voltage sense pin. Inverting node of error amplifier.
PWRGD
4
O
An open-drain output with external pullup resistor required. Asserts low if buck output voltage is low
due to thermal shutdown, dropout, overvoltage, or EN_BUCK shut down
nOCTW
5
O
Overcurrent and/or overtemperature warning indicator. This output is open drain with external pullup
resistor required. Programmable output mode via SPI registers.
nFAULT
6
O
Fault report indicator. This output is open drain with external pullup resistor required.
DTC

I
Dead-time adjustment with external resistor to GND
nSCS
