製品概要The ADP1876 is a dual-channel, step-down switching controller with integrated drivers for external N-channel synchronous power MOSFETs. The two PWM outputs are phase shifted 180°, which reduces the input rms ripple current, thus minimizing the required input capacitance.
In addition, boost diodes are integrated into the ADP1876, which lowers the overall system cost and component count. The ADP1876 is configured to operate in forced PWM continuous conduction mode.
The ADP1876 includes externally adjustable soft start, output overvoltage protection, externally adjustable current limit, power good and tracking function for Channel 1. The ADP1876 provides an output voltage accuracy of ±0.85% for a −40°C to +85°C junction temperature and ±1.5% for a −40°C to +125°C junction temperature. This controller can be powered from a 2.75 V to 20 V supply and is available in a 32-lead, 5 mm × 5 mm lead frame chip scale package (LFCSP).
