AMC3100 Datasheet, PDF (2/10 Pages) ADDtek Corp – 1.5MHz, 600mA SYNCHRONOUS STEP-DOWN CONVERTER

AMC3100
Pin Number Pin Name
PIN DESCRIPTION
Pin Function
Enable pin. Higher than 1.5V to turn on the device. Lower than 0.3V to turn it off.
1
RUN
The shutdown mode supply current less than <1µA supply current. This pin should
not be floating.
2
GND
Ground
3
SW
Power Switch Output. Connects to the drains of the internal P-CH and N-CH
MOSFET switches.
4
V_IN
Supply Input Pin.
V_FB (AMC3100): Feedback Input Pin. Connect V_FB to the center point of the
5
V_FB/V_OUT
external resistor divider. The feedback threshold voltage is 0.6V.
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, θ_JA
Note :
Junction Temperature Calculation: T_J = T_A + (P_D x θ_JA).
P_D: Power Dissipation, T_A: Ambient temperature, θ_JA: Thermal Resistance-Junction to Ambient
The θ_JA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
