I/O Description
P Ground
I
Feedback input pin. The PWM duty cycle is determined by voltage level into this pin
and the current-sense signal at Pin 4.
Dual function pin. Either connected through a NTC resistor to ground for over
I temperature shutdown/latch control or connected through Zener to VDD for
adjustable over voltage protection
I Current sense input
P Power Supply
O Totem-pole gate driver output for power Mosfet
