XC6371/XC6372 Series PWM,PWM/PFM Controlled Step-up DC/DC Converters ETR04002-006 ☆Green Operation patible - GENERAL DESCRIPTION The XC6371/XC6372 series is a group of PWM controlled and PWM/PFM controlled step-up DC/DC converters. The built-in 1.4Ω switching transistor type enables a step-up circuit to be configured using only three ponents, a coil, a diode, and a capacitor. Output voltage can be selectable in the range from 2.0V to 7.0V in increments of 0.1V (accuracy:±2.5%). Oscillation frequency is also selectable from 50k Hz, 100k Hz, and 180k Hz (accuracy:±15%) for the XC6371 and the XC6372 series. Softstart time is internally set and offers protection against in-rush currents when the power is switched on and prevents voltage overshoot. Packages with CE (chip enable) pin are also available which can reduce the IC power consumption during during stand-by mode. The XC6371 series is the standard PWM controlled products. The control of the XC6372 series switches from PWM to PFM control during light loads when automatically switching is selected and the series is highly efficient from light loads to large output currents. - APPLICATIONS - Smart phones / Mobile phones - Note PCs / Tablet PCs - Digital Still Cameras / Camcorders - Mobile devices / terminals - Features Operation Start Voltage Range : 0.9V ~ 10V Output Voltage Range Highly Accurate Oscillation Frequency : 2.0V ~ 7.0V (0.1V increments) : ±2.5% : 50k Hz, 100k Hz, 180k Hz (±15%) Maximum Output Currents : 100m A(TYP.) @ VIN=3.0V, VOUT=5.0V - Highly Efficient : 85%(TYP.) @ VIN=3.0V, VOUT=5.0V - Built-in switching transistor.
