Product Details
The ADP1877 is a Flexmode® (proprietary architecture of Analog Devices, Inc.), dual-channel, step-down switching controller with integrated drivers that drive N-channel synchronous power MOSFETs. The two PWM outputs are phase shifted 180°, which reduces the input RMS current, thus minimizing required input capacitance.
The boost diodes are built into the ADP1877, thus lowering the overall system cost and component count. The ADP1877 can be set to operate in pulse skip high efficiency mode under light load or in PWM continuous conduction mode.
The ADP1877 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 ADP1877 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.
