Functional Pin Descriptions
VSEN1 (Pin 22)
This pin is connected to the PWM converter’s output voltage.
The PGOOD and OVP comparator circuits use this signal to
report output voltage status and for over-voltage protection.
OCSET1 (Pin 23)
Connect a resistor (R
OCSET
) from this pin to the drain of the
respective upper MOSFET. R
OCSET
, an internal 200
μ
A
current source (I
OCSET
), and the upper MOSFET on-
resistance (r
DS(ON)
) set the converter over-current (OC) trip
point according to the following equation:
An over-current trip cycles the soft-start function. Sustaining
an over-current for 2 soft-start intervals shuts down the IC.
Additionally, OCSET1 is an output for the inverted FAULT
signal (FAULT). If a fault condition causes FAULT to go high,
OCSET1 will be simultaneously pulled to ground though an
internal MOS device (typical r
DS(ON)
= 100
).
