Pin Description
MIC2130/1
Pin Number
MLF-16

Pin Number
e-TSSOP-16

Pin Name
HCL *
AGND2
Pin Function
High Current Limit (Output): The capacitor on this pin sets
the duration of time so that the current limit will be set to
200% of its nominal set current. AGND2 for MIC2130

SS
Soft Start (Output): Active at Power-up, Enable, and Current
Limit recovery.

FB
Feedback (Output): Input to error amplifier. Regulates to
0.7V.

COMP
AGND1
EN/UVLO
Compensation (Output): Pin for external compensation.
Analog Ground.
Enable (Input): Logic low turns the IC off. When the voltage
drops below the band gap reference voltage of the IC the
device turns off. This accurate threshold allows the pin to be
used as an accurate under voltage lockout.

VIN
VDD
Supply Voltage (Input): 8V to 40V.
5V Internal Linear Regulator from VIN. When VIN is <8V,
this regulator operates in drop-out mode. Connect external
bypass capacitor.

LSD
Low-Side Drive (Output): High-current driver output for
external low-side MOSFET.

PGND
SW
HSD
Power Ground: High current return for ext. Low side driver.
Switch Node (Output): High current output driver return.
High-Side Drive (Output): High current output-driver for ext.
high-side MOSFET.
13
15
BST
Boost (Output): Provides voltage for high-side MOSFET
driver. The gate drive voltage is higher than the source
voltage by VDD minus a diode drop.
14
16
CS
Current Sense (Output): Current-limit comparator non
inverting input. The current limit is sensed across the low-
side FET during the OFF time. Current limit is set by the
resistor in series with the CS pin.
15

AVDD
Analog Supply Voltage (internal 5V LDO): Connect external
By pass capacitor.
16
2
PGOOD
Power Good (Output): High output when VOUT > 90%
nominal.
Note: * indicates that is only used on MIC2131.
