AiT Semiconductor Inc. www.ait-ic.com   A7106 600mA, 1.5MHz CONSTANT FREQUENCY CURRENT MODE PWM STEP-DOWN DC-DC CONVERTER DESCRIPTION The A7106 is a constant frequency, 1.5MHz, slope compensated current mode PWM step-down converter working under an input voltage range of 2.5V to 5.5V. This feature makes the A7108 suitable for single cell Li-ion battery-powered applications. The internal synchronous rectifier is desired to increase efficiency without an external Schottky diode. 100% duty cycle capability extends battery life in portable devices, while the quiescent current is 180μA at no load, and drops to < 1μA in shutdown. Pulse Skipping Mode operation increases efficiency at light loads, further extending battery life.
