VSEN (pin 1)
sets the soft-start interval of the converter.
Connect this pin to the converter’s voltage output.
The PGOOD and OVP comparator circuits monitor
output voltage status and act over voltage protection
by using this signal.
OCSET(pin 2)
Connect a resistor(R ) from this pin to the drain
OCSET
of the upper MOSFET. An internal 200mA current
source (IOCS), ROCSET, and the upper MOSFET’s on-
resistance (R ) set the converter over-current
DS(ON)
(OC) trip point according to the following equation:
IPEAK= IOCS´ ROCSET /RDS(ON)
An over-current trip resets the soft-start function.
SS (Pin 3)
Connect a capacitor from this pin to ground. This
capacitor, along with an internal 10mA current source,
VID0-4 (Pins 4-8)
VID0-4 are the input pins to the 5-bit DAC. The states
of these five pins decide the internal voltage refer-
ence (DACOUT). The level of DACOUT sets the con-
verter output voltage and also sets the PGOOD and
OVP thresholds. Table 1 specifies DACOUT for the
32 combinations of DAC inputs.
COMP (pin 9) and FB (pin 10)
COMP and FB are the accessiable pins of the error
amplifier. FB pin is the inverting input of the error
amplifier and COMP pin is output of the error amplifier.
These pins provide the compensation for the volt-
age-control feedback loop of the converter.
GND (Pin 11)
GND is signal ground of the IC. All voltage levels are
measured with respect to this pin.
