Product Summary

The ADP2118ACPZ-R7 is a low quiescent current, synchronous, step-down, dc-to-dc converter in a compact 4mm × 4mm LFCSP_WQ package. It uses a current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. Under light loads, the ADP2118ACPZ-R7 can be configured to operate in pulse frequency modulation (PFM) mode that reduces switching frequency to save power. The ADP2118 runs from input voltages of 2.3 V to 5.5 V. The output voltage of the ADP2118ACPZ-R7 is adjustable from 0.6 V to input voltage (VIN). The ADP2118ACPZ-R7 requires minimal external parts and provides a high efficiency solution with its integrated power switch, synchronous rectifier, and internal compensation.
