XC9213B

The XC9213B is designed as one member of the XC9213 series which are N-ch & N-ch drive, synchronous, step-down DC/DC controller ICs with a built-in bootstrap driver circuit. Output will be stable no matter which load capacitors, including low ESR capacitors, are used. Typical applications include PDAs, mobile phones, note book computers, portable audio systems and various multi-function power supplies.

XC9213B has thirteen features. (1)Its input voltage range is from 4.0V to 25V. (2)Its output voltage range is from 1.5V to 15V with externally set reference voltage is 1.0V. (3)Its oscillation frequency is 300kHz. (4)Its output current is more than 5A. (5)Its control is PWM /PFM manual switching control. (6)Its current limiter means current limit operates at voltage. (7)Its protection is sense 170mV typ and shutdown time can be adjustabled by CPRO. (8)High efficiency 93%. (9)Detect voltage function. (10)Standby current 4.0A max. (11)Load capacitor low ESR capacitor compatible. (12)Synchronous bootstrap N-ch & N-ch driver. (13)Package is TSSOP-16. That are all the main features.
