XC9303 Series
High Efficiency, Synchronous Step-Up & Down DC / DC Controller ICs
ETR0602_005
☆Green Operation Compatible
■GENERAL DESCRIPTION
The XC9303 series is highly efficient, synchronous PWM, PWM/PFM switchable step-up & down DC/DC controller ICs. A versatile, large output current and high efficiency, step-up/down DC/DC controller can be realized using only basic external components - transistors, coil, diode, capacitors, and resistors for detecting voltages. High efficiency is obtained through the use of a synchronous rectification topology. The operation of the XC9303 series can be switched between PWM and PWM/PFM (auto switching) externally using the PWM pin.
