ADP2116ACPZ

开关稳压器 Cnfgrble Dual 3A/SGL 6A Sync Step-Down

Configurable, Dual 3 A/Single 6 A,  Synchronous, Step-Down DC-to-DC Regulator

GENERAL DESCRIPTION ADP2116ACPZ

The ADP2116 is a versatile, synchronous, step-down switching

regulator that satisfies a wide range of customer point-of-load

requirements. The two PWM channels can be configured to deliver

independent outputs at 3 A and 3 A (or at 3 A and 2 A) or can be

configured as a single interleaved output capable of delivering 6 A.

The two PWM channels are 180° phase shifted to reduce input

ripple current and input capacitance.

FEATURES ADP2116ACPZ
