Description

The totem-pole output driver to drive the power MOSFET

Power supply

No connection

Current-sense detects the voltage across a sensed resistor. To provide over-

current protection, PWM output is disabled if the voltage exceeds an internal

threshold. This pin also provides current information for current-mode control.

No connection

No connection

The FB pin provides feedback information to the internal PWM comparator. This

feedback is used to control the duty cycle.
