Pin Description
SGND
–
Common connection for all low level signal and
digital circuits. While SGND and PGND must be
electrically connected together, having separate
common pins enhances the ability of the designer
to prevent coupling of noise into critical circuits.
PGND
–
This pin provides common return for the high
transient current of the output driver circuits. While
PGND and SGND must be electrically connected,
having a separate connection prevents common
noise created by the high transient currents of the
output driver from being injected into critical circuits.
+V
IN
–
This is the start-up linear pre-regulator input which
can accept DC input voltages in the range of 15V
to 250V. With START and STOP set to more than
20V, the leakage current on this pin is less than
6.0
μ
A at +V
IN
= 20V.
The resistive divider from +V
IN
sets the start voltage.
The resistive divider from +V
IN
sets the stop voltage.
This is the supply pin for the PWM circuits. When
the input voltage to the +V
IN
pin exceeds the start
voltage the input regulator seeks to regulate the
voltage on the capacitor connected to this pin to a
nominal 4.5V.

OUT
–
This high current push-pull CMOS output is intended
to drive the gate of a power MOSFET. In order to
protect the power MOSFET in high electrical noise
environment, this output appears as low impedance
to PGND when V
DD
is at zero volts.
This is the current sense input to the PWM
comparators. Under normal operation the over
current limit is triggered when the voltage on this
pin is at 0.70V and the loop control operating peak
current may be set to any level below this, typically
in the range of 0.2 to 0.5V.
CS
–
COMP
–
The low impedance output of the error amplifier.
FB
–
The high impedance inverting input of the error
amplifier.
NI
–
The high impedance non-inverting input of the error
amplifier.
REF
–
This pin provides a 2% accuracy 1.25V low output
impedance buffered reference which is current
limited to 0.5mAmps and should be bypassed,
REF to SGND, with a 0.1
μ
F ceramic capacitor.
RT
–
The resistor connected from this pin to SGND sets
the frequency of the internal oscillator by setting
the charging current for the internal timing capacitor.
The oscillator frequency is twice the PWM output
frequency.
STATUS –
This output is held low until the +V
IN
voltage reaches
the programmed START voltage. It remains low
until the bootstrap supply to V
DD
forces the voltage
above the internal regulator set point. It is further
held low while the control amplifier output on the
COMP pin is forced to its high limit by a low output
from the converter. Once all these conditions are
satisfied, this output will rise to V
DD
with a time
constant set by the external capacitor indicating
that normal operation has been reached. This
output may be used to control the reset of a
microprocessor.
