Power Integrations, Inc 

INT200

Pin Functional Description

Pin 1:

Active-low logic-level input HS IN

controls the pulse circuit which signals

the INT201 high-side driver.

Pin 2:

Active-high logic level input LS IN

controls the low side driver output.

Pin 3:

LS OUT is the driver output which

controls the low-side MOSFET.

Pin 4:

COM connection; analog reference point

for the circuit.

Pin 5:

Level shift output HSD 2 signals the

high-side driver to turn off. One short,

precise pulse is sent on each positive

transition of HS IN.

Pin 6:

Level shift output HSD 1 signals the

high-side driver to turn on. Two short,

precise pulses are sent on each negative

transition of HS IN.

Pin 7:

N/C for creepage distance.

Pin 8:

V supplies power to the logic, high-

DD

side interface, and low-side driver.
