HX1001D
Synchronous Buck DC/DC Converter
Feature Up to 95% Efficiency Current Mode Operation for Excellent Line and Load Transient Response 1.2A Output Current Low Quiescent Current: 300μA Output Voltage: 0.6V ～ 5.5V Automatic PWM/PFM Mode Switching No Schottky Diode Required Frequency Operation: 1.3MHz Short-Circuit Protection Shutdown Quiescent Current: <1μA Low Profile SOT-23-5L Package (lead-free packaging is now available) Application Car Charger / Adaptor Pre-Regulator for Linear Regulators Distributed Power Systems Battery Charger Description The HX1001D is high efficiency synchronous, PWM step-down DC/DC converters working under an input voltage range from 2.2V to 5.5V. This feature makes the HX1001D suitable for single Li-Lon battery-powered applications. 100% duty cycle capability extends battery life in portable devices, while the quiescent current is 300μA with no load, and drops to <1μA in shutdown. The internal synchronous switch is desired to increase efficiency without an external Schottky diode. The 1.3MHz switching frequency allows the using of tiny, low profile inductors and ceramic capacitors, which minimized overall solution footprint. The HX1001D converters are available in the industry standard SOT-23-5L power packages (or upon request)
