XC6368

XC6367/XC6368 Series PWM Controlled, PWM/PFM Switchable Step-up DC/DC Controllers ETR0401_006 ☆Green Operation Compatible ■GENERAL DESCRIPTION The XC6367/XC6368 series are multi-functional step-up DC/DC controllers which provide high efficiency outputs by using an externally connected transistor, coil, diode and capacitor. Output voltage is selectable in 0.1V increments within a range of 1.5V ~ 6.5V (±2.5%). For output voltages outside this range, we recommend FB version, which has a 1.0V internal reference voltage. Using the FB version, the required output voltage can be set-up using 2 external resistors. With a 300kHz oscillation frequency, the size of the external components can be reduced. Control switches from PWM to PFM during light loads with the XC6368 (PWM/PFM switchable) and the series is highly efficient from light loads to large output currents. Soft start time of XC6367/ XC6368A, B, and E series is internally set to 10ms and XC6367/68C, D, and F series regulate soft-start time by connecting resistors and capacitors externally. During stand-by (CE pin "L"), supply current is reduced to less than 0.5μA. ■APPLICATIONS ●E-book Readers / Electronic dictionaries ●Smart phones / Mobile phones ●Note PCs / Tablet PCs ●Digital audio equipments ●Multi-function power supplies ■FEATURES Input Voltage Range : 0.9V ~ 10V Operating Voltage Range : 2.0V ~ 10V Output Voltage Range : 1.5V ~ 6.5V (0.1V increments) (±2.5%) Oscillation Frequency : 300kHz, 100kHz (±15%) Custom...
