The STODD03 is a 2-channel power management device intended for Blu-Ray applications based on high density optical storage devices. It integrates one step-down converter able to provide 3.3V fixed output voltage up to 700mA load, and one step-up converter to provide the power supply needed for the blue laser in applications where only 5V input voltage is available. The step-up output voltage is adjustable in the range from 6.5V to 14V, with current capability up to 500mA. Both step-down and step-up channels integrate low RDS_ON N-channel and P-channel MOSFETs, allowing high DC-DC efficiencies. The STODD03 has a 1A integrated power switch.
The STODD03 is a monolithic 2-channel power management device designed for high-density optical storage devices, such as Blu-Ray players. It integrates a step-down converter providing a fixed 3.3 V output up to 700 mA and a step-up converter adjustable from 6.5 V to 14 V with up to 500 mA capability. The device also features an integrated 1 A power switch for motor control.
