AiT Semiconductor Inc. www.ait-ic.com A7131 DC-DC CONVERTER 3A 1.5MHz 5.5V SYNCHRONOUS BUCK CONVERTER DESCRIPTION FEATURES The A7131 is a high efficiency synchronous, buck  DC/DC converter. Its input voltage range is from 2.6V  Adjustable Output Voltage, VFB=0.8V Maximum output current is 3A to 6V and provides an adjustable regulated output  Range of operation input voltage: Max 6V voltage from 0.8V to 5.5V while delivering up to 3A of  Standby current: 0.5mA (typ.) output current.  Line regulation: 0.1%/V (typ.)  Load regulation: 10mV (typ.) The internal synchronous switches increase  High efficiency, up to 96% efficiency and eliminate the need for an external  Environment Temperature: -20°C~85°C Schottky diode. The switching frequency is set by an  Available in DFN8(2x2) and DFN10(3x3) external resistor or can be synchronized to an Packages external clock. The 100% duty cycle provides low dropout operation extending battery life in portable APPLICATION systems.  Power Management for 3G modem The A7131 is operated in PFM/PWM auto-switch  mode which enhance the efficiency at light-load.  3W LED driver from Li-ion battery LCD Monitor and LCD TV  The A7131 is available in DFN8(2x2) and  DFN10(3x3) packages.  DVD Decode Board ADSL Modem Post Regulators for Switching Supplies ORDERING INFORMATION TYPICAL APPLICATION Package Type Part Number DFN8 A7131J8R J8 A7131J8VR DFN10 A7131J10R J10 A7131J10VR Note R: Tape & Reel V: Halogen f...
