ADI ADP1877ACPZ-R7

降压降压2.75V ~ 14.5V

Overview

The boost diodes are built into the ADP1877, thus lowering the overall system cost and component count. The ADP1877ACPZ-R7 can be set to operate in pulse skip high efficiency mode under light load or in PWM continuous conduction mode.

The ADP1877ACPZ-R7 includes externally adjustable soft start, output overvoltage protection, externally adjustable current limit, power good, and a programmable oscillator frequency that ranges from 200 kHz to 1.5 MHz. The ADP1877ACPZ-R7 provides an output voltage accuracy of ±0.85% from −40°C to +85°C and ±1.5% from −40°C to 125°C in junction temperature. This part can be powered from a 2.75 V to 14.5 V supply, operates over the −40oC to +125oC junction temperature range, and is availa-ble in a 32-lead 5 mm × 5 mm LFCSP package.
