The MCP16311T-E/MNY is a high-efficiency synchronous step-down DC-DC converter capable of handling input voltages from 4.4V to 30V and providing an output current of up to 1A. It features an adjustable output voltage range from 2.0V to 24V, making it suitable for various applications including automotive battery regulation and general-purpose DC-DC conversion. The device operates with efficiencies up to 95% and includes integrated high-side and low-side switches with low on-resistances of 300 mOc and 170 mOc, respectively. This regulator supports both Pulse Frequency Modulation (PFM) and Pulse Width Modulation (PWM) operation, with a typical switching frequency of 500 kHz in PWM mode. It has a low shutdown current of 3 ¬µA and a quiescent current of 44 ¬µA in non-switching PFM mode, which enhances its efficiency during light load conditions. The MCP16311T-E/MNY also incorporates features such as undervoltage lockout, overtemperature protection, and internal soft-start, ensuring reliable operation across a wide temperature range of -40¬8C to +125¬8C. The device is available in compact MSOP-8 and TDFN-2x3mm packages, making it suitable for space-constrained designs.
