Pin Description
Pin Number
Pin Name
Pin Function
1S 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.
3FB
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 (<1µA) when disabled.
5V
IN
Supply Voltage: 3.0V to 40V
6P GND 2
Power Ground #2: One of two NPN power switch emitters with 0.3Ω current
sense resistor in series. Required. Connect to external inductor or input
voltage ground depending on circuit topology.
7V
SW
Power Switch Collector: Collector of NPN switch. Connect to external
inductor or input voltage depending on circuit topology.
8P GND 1
Power Ground #1: One of two NPN power switch emitters with 0.3Ω 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.
8-pin DIP (N)
