JWH6344 High Efficiency Synchronous Step-Down PWM Controller Preliminary Specifications Subject to Change without Notice DESCRIPTION FEATURES The JW ®H6344 is a synchronous buck regulator controller. Operating with an input range of 5V~65V, the JWH6344 adopts voltage mode control and provides high efficiency, excellent transient response, and high DC output accuracy needed for low output voltage, high current, PC system power rail and similar POL power supply in digital consumer products. At light loads, the regulator operates in low frequency to maintain high efficiency.  5V to 65V operating input range 0.8V to 65V output voltage range Built-in ±1% 0.8V reference voltage Switching frequency from 100kHz to 1MHz -SYNC In and SYNC Out capability 7.5V gate drivers for standard VTH MOSFETs -14ns dead time -2.3A source and 3.5A sink capability -Low-side soft-start for pre-bias start-up Programmable current limit by low side RDS(ON) sensing or shunt sensing Adjustable soft-start or optional voltage tracking Built-in OCP/UVP Power good indicator Thermal protection Available in QFN3.5X4.5-20 package      The JWH6344 guarantees robustness with thermal protection, short-circuit protection, over current protection, output over-voltage protection, output under-voltage protection and input under voltage lockout.     The JWH6344 is available in QFN3.5X4.5-20 package, which provides a compact solution with minimal external components.  APPLICATIONS Company’s Logo is Protected, “JW” and “JOULWATT” are Registered  Trademarks of JoulWatt technology Inc.
