The input supply for the PWM regulator power stage.

Connected to DRAIN of the high side MOSFET.

A resistor to VIN and a capacitor to GND determine the frequency of the saw-tooth oscillator.

of this next generation of DC/DC converter include pulse-by-pulse current limit for FET protection, hiccup mode for short circuit protection, voltage feedforward regulation, Frequency SYNC, soft-start, low standby current of 60µA typical in the disabled state, and thermal shut-down. The device is available in a 20 Ld HTSSOP package. Features.
Voltage feedforward mode.
Step down DC/DC supporting up to 2A.
Input voltage range of 9.0V to 40V.
Internal reference.
