FDZ2040L
Integrated Load Switch
Features
 Optimized for low-voltage core ICs in portable systems
 Very small package dimension: WL-CSP 0.8X0.8X0.5
mm³
 Current = 1.2 A, V_IN max = 4 V
 Current = 2 A, V_IN max = 4 V (Pulsed)
 R_DS(ON) = 80 mΩ at V_ON = 0 V, V_IN = 4 V
 R_DS(ON) = 85 mΩ at V_ON = 0 V, V_IN = 3.6 V
 R_DS(ON) = 90 mΩ at V_ON = 0 V, V_IN = 3 V
 RoHS Compliant
General Description
This device is particularly suited for compact power
management in portable application where 1.6V to 4V input
and 1.2A output current capability are needed. This load
switch integrates a level shifting function that drives a P-
Channel Power MOSFET in the very small 0.8X0.8X0.5 mm³
WL-CSP package.
Applications
 Load switch
 Power management in portable applications
