AMC3100
PIN DESCRIPTION
Pin Function
Pin Number
Pin Name
Enable pin. Higher than 1.5V to turn on the device. Lower than 0.3V to turn it off.
The shutdown mode supply current less than <1µA supply current. This pin should
not be floating.

Power Switch Output. Connects to the drains of the internal P-CH and N-CH
MOSFET switches.
VIN
Supply Input Pin.
VFB (AMC3100): Feedback Input Pin. Connect VFB to the center point of the
external resistor divider. The feedback threshold voltage is 0.6V.

VFB/VOUT
V
OUT (AMC3100-X.X): Output Voltage Feedback Pin. An internal resistive divider
divides the output voltage down for comparison to the internal reference voltage.
PACKAGE THERMAL DATA
Thermal Resistance from Junction to Ambient, θJA
250 OC /W
Note :
Junction Temperature Calculation: TJ = TA+ (PD x θJA).
PD: Power Dissipation, TA: Ambient temperature, θJA: Thermal Resistance-Junction to Ambient
The θJA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
