概述

The RP602 is a 6.5 V (Max. rating) buck-boost DC/DC converter with synchronous rectifier. This device is ideally suited for industrial or OA equipment that require constant voltage even when low-input voltage (Min. 2.3 V). Since operating with switching frequency of 2.6 MHz, this device can realize a high-speed response with a small coil and maintain a high-efficiency at low input voltage.

Key Benefits

Realize a high-efficiency at low input voltage.
Provide output voltage of 2.7 to 4.2 V corresponding to input voltage of 2.3 to 5.5 V.
