I/O DESCRIPTION

NAME VSON
PowerPAD
A bootstrap capacitor is required between the BOOT and PH pins. If the voltage
BOOT 1 9 O on this capacitor is below the minimum required by the output device, the output is
forced to switch off until the capacitor is refreshed.
This pin is the error-amplifier output and the input to the output switch-current
COMP 6 7 O
comparator. Connect frequency compensation components to this pin.
EN 7 8 I This pin is the enable pin. Float the EN pin to enable.
3
GND 4 4 — Ground
5
PH 3 2 O The PH pin is the source of the internal high-side power MOSFET.
RT (TPS54335A Connect the RT pin to an external timing resistor to adjust the switching frequency
and TPS54335-1A) of the device.
8 10 O
The SS pin is the soft-start and tracking pin. An external capacitor connected to
SS (TPS54336A) this pin sets the internal voltage-reference rise time. The voltage on this pin
overrides the internal reference.
VIN 2 1 — This pin is the 4.5- to 28-V input supply voltage.
VSENSE 5 6 I This pin is the inverting node of the transconductance (gm) error amplifier.
PowerPAD (SO only) For proper operation, connect the GND pin to the exposed thermal pad. This
— thermal pad should be connected to any internal PCB ground plane using multiple
Thermal pad (VSON only)
vias for good thermal performance.
