The DA9231 is an ultra-low quiescent current high-efficiency buck regulator and an ultra-low quiescent current LDO in a compact I2C configurable WLCSP package targeting battery-powered applications needing highly efficient power supplies. The buck regulator extends high light-load efficiency down to 10μA further extending battery life. Dynamic Voltage Control (DVC) in the buck regulator facilitates optimization across the system power modes enabling further improvement in system efficiency and battery life. The low quiescent current LDO can be configured as a load switch and provides the second supply output. The LDO's uncommitted inputs can be connected to either the battery or the buck output. Connecting the input to the buck output provides the flexibility to improve the PSRR at the LDO output as needed. It provides multiple protection features and comes with the ability to monitor the events and indicators in the GPO pin.

The DA9232 is a high-efficiency, ultra-low quiescent current and ultra-low output ripple buck regulator in a compact I2C configurable WLCSP package targeting battery-powered applications needing low ripple and highly efficient power supplies. The battery life of these devices is significantly improved due to the low quiescent current delivered by DA9232 during operation and shutdown. Dynamic voltage control (DVC) in the buck regulator facilitates optimization across the system power modes enabling further improvement in system efficiency and battery life.

The DA9233 is a high-efficiency, ultra-low quiescent current buck regulator and ultra-low quiescent current LDO in a compact I²C configurable WLCSP package. The buck regulator also features ultra-low output ripple (<10mV). It targets battery-powered applications needing low ripple and highly efficient power supplies. The buck regulator extends high light-load efficiency down to 20μA further extending battery life. Dynamic Voltage Control (DVC) in the buck regulator facilitates optimization across the system power modes enabling further improvement in system efficiency and battery life. The low quiescent current LDO can be configured as a load switch and provides the second supply output. The LDO’s uncommitted inputs can be connected to either the battery or the buck output. Connecting the input to the buck output provides the flexibility to improve the PSRR at the LDO output as needed. DA9233 provides multiple protection features and comes with the ability to monitor the events and indicators in the GPO pin.

The DAC1008D650HN is a high-speed 10-bit dual channel Digital-to-Analog Converter (DAC) with selectable 2x, 4x or 8x interpolating filters optimized for multi-carrier WCDMA transmitters. Because of its digital on-chip modulation, the DAC1008D650 allows the complex I and Q inputs to be converted up from baseband to IF. The mixing frequency is adjusted via a Serial Peripheral Interface (SPI) with a 32-bit Numerically Controlled Oscillator (NCO) and the phase is controlled by a 16-bit register. The DAC1008D650 also includes a 2x, 4x or 8x clock multiplier which provides the appropriate internal clocks and an internal regulation to adjust the output full scale current.
