The STODD01 is a monolithic power management for high definition ODD with true shut-down, reset, and programmable step-up voltage.
The STODD01 is a complete power management solution for high-definition optical disc drives (ODD), integrating two step-down converters and one step-up converter. The step-down converters provide up to 800 mA each for low-voltage digital cores, while the step-up converter supplies up to 700 mA for blue lasers, with a programmable output voltage range of 6.5 V to 14 V via the S-Wire protocol.
The device operates at a typical switching frequency of 1.2 MHz, allowing for the use of small surface-mounted components. It includes features such as synchronous rectification, power save mode, internal soft start, reset function, and true cut-off for the step-up section. The STODD01 is available in a QFN16 (4 x 4 mm) package.
