RK809-1 Integrated Circuit Chip Power-Management IC For Multi-Core System Applications

Product Description Of RK809-1
RK809-1 is a complex power-management integrated circuit (PMIC) integrated CODEC for multi-core system applications powered by an external power supply. The RK809 can provide a complete power management solution with very few external components.
The RK809 provides five fast load transient synchronous step-down converters. The device also contains 9 LDO regulators, two switches and a battery fuel gauge. Power-up/power-down controller is configurable and can support any customized power-up/power-down sequences (OTP based). A real-time clock (RTC) is also integrated to provide a 32.768-kHz output buffer, and real time function. The RK809 supports 32.768-kHz clock generation based on a crystal oscillator. It also includes Audio CODEC , real ground Head phone driver and ClassD driver.
