ADP5034-1-EVALZ

双3兆赫， 1200毫安降压型稳压器具有两个300毫安的LDO Dual 3 MHz, 1200 mA Buck Regulators with Two 300 mA LDOs

The is an evaluation board for the ADP5034 micro power management unit PMU. The ADP5034 evaluation board has two step-down regulators with two LDOs that enable evaluation of the ADP5034. The evaluation board is available in standard voltage options. The ADP5034 uses a proprietary high speed, current mode, constant frequency, pulse-width modulation PWM control scheme for excellent stability and transient response. To ensure the longest battery life in portable applications, the ADP5034 features a power save mode PSM that reduces the switching frequency under light load conditions, as well as the option to change the mode to fixed PWM operation. The 3MHz switching frequency minimizes the size of the external components. The low quiescent current, low dropout voltage and wide input voltage range of the ADP5034 LDO regulators extend the battery life of portable devices.
