产品概述

CXSD6185  series is a group of synchronous rectification type DC/DC converters with a built-in 0.6Ω P-channel driver transistor and 0.7Ω N-channel switching transistor, designed to allow the use of ceramic capacitors. The ICs enable a high efficiency, stable power supply with an output current of 500mA to be configured using only a coil and two capacitors connected externally. With the built-in oscillator, oscillation frequency is 1.2MHz.As for operation mode, the CXSD6185 series can be manually switched with automatic PWM/PFM switching control mode, allowing fast response, low ripple and high efficiency over the full range of load (from light load to high output current conditions). During standby, all circuits are shutdown to reduce current consumption to as low as 1.0μA or less.
