Pin Functions

PIN DESCRIPTION
NAME TPS62736
RGY		 TPS62737
RGY		 TYPE
EN1 5 5 Input Digital input for chip enable, standby, and ship-mode. EN1 = 1 sets ship mode independent of EN2. EN1=0, EN2 = 0 disables the buck converter and sets standby mode. EN1=0, EN2=1 enables the buck converter.
Do not leave either pin floating.
EN2 6 6 Input
IN 1 1 Input Input supply to the buck regulator
NC 2, 3, 4, 14 4, 14 Input Connect to VSS
OUT 11 11 Output Step down (buck) regulator output
SW 13 2, 13 Input Inductor connection to switching node
Thermal Pad 15 15 Input Connect to VSS
VIN_OK 10 10 Output Push-pull digital output for power-good indicator for the input voltage.
Pulled up to VIN pin.
VIN_OK_SET 8 8 Input Resistor divider input for VIN_OK threshold. Pull to VIN to disable.
Do not leave pin floating.
VOUT_SET 9 9 Input Resistor divider input for VOUT regulation level
VRDIV 7 7 Output Resistor divider biasing voltage
VSS 12 3, 12 Input Ground connection for the device
