A7122

AiT Semiconductor Inc. www.ait-ic.com A7122 DC-DC CONVERTER BUCK (STEP-DOWN) 2A 3MHz 6V SYNCHRONOUS BUCK CONVERTER DESCRIPTION FEATURES The A7122 is a high efficiency synchronous, buck  DC/DC converter. Its input voltage range is from 2.6V  Adjustable Output Voltage, VFB=0.6V Maximum output current is 2A to 6V and provides an adjustable regulated output  Range of operation input voltage: Max 6V voltage from 0.6V to VIN while delivering up to 2A of  output current.  Standby current: 30uA (typ.) Line regulation: 0.1%/V (typ.) The internal synchronous switches increase  Load regulation: 10mV (typ.) efficiency and eliminate the need for an external  High efficiency, up to 96% Schottky diode. It runs at a fixed 3MHz frequency,  Environment Temperature: -20°C~85°C which allows the use of small inductor with L<1uH  Available in DFN8(2x2) and SOT-25 Packages while maintaining a high efficiency and small output voltage ripple. APPLICATION When Mode pin is connected to GND, the A7122 is operating in PFM/PWM auto-switch mode which  Power Management for 3G modem enhance the efficiency at light-load.  Smart Phone  Tablet PC The A7122 is available in DFN8(2x2) and SOT-25  Set Top Box packages.  Other Battery Powered Device ORDERING INFORMATION TYPICAL APPLICATION Package Type Part Number DFN8(2x2) A7122J8R J8 A7122J8VR SOT-25 Note A7122E5R E5 A7122E5VR R: Tape & Reel V: Halogen free Package AiT provides all RoHS products Suffix “ V “ means Ha...
