DA9024 DA9024 quad 1.2a buck pmic with audio drivers the DA9024 is a quad buck 1.2a per channel pmic with 20 linear regulators, an integrated, class-g, true-ground capless headphone driver, and a class d speaker driver, enabling supply domain fexibility to support associated peripherals and user interface functions. controlled by a programmable digital power manager the user-programmable switched and linear regulators have confgurable startup sequences, levels and timing. for optimal processor energy- per-task performance dynamic voltage scaling is available on four supply domains. all linear regulators use dialogs smart mirror? dynamic biasing technique which maintains high performance over a wide range of operating conditions and a power saving mode (sleep mode) to minimize the quiescent current. the regulators have output voltages independently programmable via the device control interface. the buck converters do not require external schottky diodes and of fer a sleep mode (pfm mode) for optimal effciency at low load currents. all converters use a high switching frequency (2mhz) allowing the use of small 2.2uh external inductors. a backup battery charger and an ultra-low power real-time-clock (rtc) are also implemented on the ic. the DA9024 contains a class-g true-ground capless headphone driver and a class d speaker driver, with power-limiter, along with two differential or four single ended input channels with analog routing/mixing. the DA9024 is controlled by a bidirectional i2c interface and can operate in standard mode (up to 400khz) and high speed mode (up to 1.7mhz) allowing for a highly fexible confguration of end applications. www.dialog-semiconductor.com
