XC9257/XC9258 Series

COT Control, 1.0A Synchronous Step-Down DC/DC Converters

ETR05040-001

☆GreenOperation-compatible

■GENERAL DESCRIPTION

The XC9257/XC9258 series is a group of synchronous-rectification type DC/DC converters with a built-in P-channel MOS driver

transistor and N-channel MOS switching transistor, designed to allow the use of ceramic capacitors. Output voltage is internally

set in a range from 0.8V to 3.6V (accuracy: ±2.0%) increments of 0.05V. The device provides a high efficiency, stable power

supply with an output current of 1.0A to be configured using only a coil and two capacitors connected externally. Oscillation

frequency is set to 1.2MHz or 6.0MHz can be selected for suiting to your particular application.

As for operation mode HiSAT-COT ^(*)control excellent in transient response, the XC9257 series is PWM control, the XC9258

series is automatic PWM/PFM switching control, allowing fast response, low ripple and high efficiency over the full range of loads

(from light load to heavy load).

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 0.3ms in typical for quick turn-on. With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel MOS

driver transistor is forced OFF when input voltage becomes 2.00V or lower. The B types integrate C_LHigh Speed discharge

function which enables the electric charge at the output capacitor C_Lto be discharged via the internal discharge.

Two types of package SOT-25, USP-6C are available.

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