The ADP5033 evaluation board is a two-step-down regulator with a two-LDO solution that enables evaluation of the ADP5033. The evaluation board is available in standard voltage options.
The ADP5033 uses a proprietary high speed, current mode, constant frequency PWM control scheme for excellent stability and transient response. To ensure the longest battery life in portable applications, the ADP5033 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 3 MHz switching frequency minimizes the size of the external components.
The low quiescent current, low dropout voltage, and wide input voltage range of the ADP5033 LDO extends the battery life of portable devices.
