Pin Description
Pin Number
Pin Name
Pin Function
1
S GND
Signal Ground: Internal analog circuit ground. Connect directly to the input
filter capacitor for proper operation (see applications info). Keep separate
from power grounds.
2
COMP
Frequency Compensation: Output of transconductance type error amplifier.
Primary function is for loop stabilization. Can also be used for output voltage
soft-start and current limit tailoring.
3
FB
Feedback: Inverting input of error amplifier. Connect to external resistive
divider to set power supply output voltage.
4 (MIC2172)
SYNC
Synchronization/Frequency Adjust: Capacitively coupled input signal greater
than device’s free running frequency (up to 135kHz) will lock device’s
oscillator on falling edge. Oscillator frequency can be trimmed up to 135kHz
by adding a resistor to ground. If unused, pin must float (no connection).
4 (MIC3172)
EN
Enable: Apply TTL high or connect to V
IN
to enable the regulator. Apply
TTL low or connect to ground to disable the regulator. Device draws only
leakage current (<1
μ
A) when disabled.

V
IN
Supply Voltage: 3.0V to 40V
6
P GND 2
Power Ground #2: One of two NPN power switch emitters with 0.3
current
sense resistor in series. Required. Connect to external inductor or input
voltage ground depending on circuit topology.
7
V
SW
Power Switch Collector: Collector of NPN switch. Connect to external
inductor or input voltage depending on circuit topology.
8
P GND 1
Power Ground #1: One of two NPN power switch emitters with 0.3
current
sense resistor in series. Optional. For maximum power capability connect
to P GND 2. Floating pin reduces current limit by a factor of two.
