XC9274/XC9275Series

ETR05056-001

COT Control, 3.0A Synchronous Step-Down DC/DC Converters

☆Green Operation-compatible

■GENERAL DESCRIPTION

The XC9274/XC9275 series is a group of synchronous-rectification type DC/DC converters with a built-in 51mΩ P-channel

MOS driver transistor and 49mΩ N-channel MOS switching transistor, designed to allow the use of ceramic capacitors. The

small on-resistances of these two internal driver transistors enable a high efficiency, stable power supply with an output current

up to 3.0A. A 0.6V reference voltage source is incorporated, and the output voltage can be set freely by external resistors.

Oscillation frequency is set to 1.2MHz or 3.0MHz can be selected for suiting to your particular application. The operation mode is

HISAT-COT (*) control , which has an excellent transient response, the XC9274 series is PWM control, the XC9275 series is

PWM/PFM auto switching control, allowing fast response, low ripple, and high efficiency over the full range of loads (from light

loads to heavy loads).

During stand-by, all circuits are shutdown to reduce current consumption to as low as 1.0μA or less. As for the soft-start

function as fast as 0.25ms in typical for quick turn-on. Internal protection circuits include over current protection, short-circuit

protection, and thermal shutdown circuits to enable safe use. Short-circuit protection is available only for B,C type. Hiccup mode

is available only for D,E type. Soft-off function is available only for B, D type. The package is the SOP-8FD.

(*) HiSAT-COT is an original Torex term for High Speed Transient Response.
