(1) See the TPSM63602, TPSM63603, TPSM63604, and TPSM63606 for applications that require clock synchronization, an output
voltage above 6 V, spread-spectrum modulation for EMI mitigation or both.

Input supply voltage. Connect the input supply to these pins. Connect input capacitors between these
pins and PGND in close proximity to the device.

P
Switch node. Do not place any external component on this pin or connect to any signal. The amount of
copper placed on this pin must be kept to a minimum to prevent issues with noise and EMI.

O
Bootstrap pin for the internal high-side gate driver. A 100-nF bootstrap capacitor is internally connected
from this pin to SW within the module to provide the bootstrap voltage. CBOOT is brought out to use in
conjunction with RBOOT to effectively lower the value of the internal series bootstrap resistance to adjust
the switch-node slew rate, if necessary.

P
External bootstrap resistor connection. Internal to the device, a 100-Ω bootstrap resistor is connected
between RBOOT and CBOOT. RBOOT is brought out to use in conjunction with CBOOT to effectively
lower the value of the internal series bootstrap resistance to adjust the switch-node slew rate, if
necessary.

5
Input bias voltage. Input to the internal LDO that supplies the internal control circuits. Connect to an
output voltage point to improve efficiency. Connect an optional high-quality 0.1-μF to 1-μF capacitor from
this pin to ground for improved noise immunity. If the output voltage is above 12 V, connect this pin to
ground.
