<p align="justify">The RT9953 is a complete power supply solution for digital still cameras and other handheld devices. The RT9953 is a multi-channel power management IC including one synchronous step-up DC/DC converter, one selectable synchronous step-up/step-down DC/DC converter, two synchronous step-down DC/DC converters, and one low dropout linear regulator.<br />The RT9953 is designed to fulfill the applications for DSC as follows :<br />CH1 is a synchronous step-up output for motor or DSC system I/O power<br />CH2 is a selectable synchronous step-up/step-down output for motor or DSC system I/O power<br />CH3 and CH4 are synchronous step-down outputs for DSP core and memory power supply<br />CH5 is a 500mA, low dropout, low noise linear regulator with soft-start function.<br />The RT9953 is designed to support Li+ and 2AA battery applications. The selectable step-up/step-down converter can be set by SEL pin. For the synchronous step-up and step down converters, the efficiency can be up to 95%.<br />The RT9953 provides over current protection, thermal shutdown protection, over voltage and under voltage protection to achieve complete protection. The RT9953 is available in the WQFN-24L 4x4 package.</p>
