Six-channel power management IC

20 August 2008 Power Electronics / Power Management

AnalogicTech's AAT2603 is a power management IC with six channels, which operates off a 2,7 V to 5,5 V input range. Delivering with only 200 mV of headroom, the first step-down converter supports functions requiring high output current and low dropout voltage. The second step-down converter supplies 600 mA and adds a two-step dynamic output voltage capability to match the needs of common system processors. The converter dynamically shifts between the two output voltages by toggling a device pin. Four LDOs supply power to a variety of system functions. Two LDOs deliver 200 mA and are designed to power noise sensitive circuits. The second pair of LDOs offers 400 mA output. Each of the four LDOs consumes just 50 μA of quiescent current. The IC also features protection for short-circuit, over-current and over-temperature conditions.
