The wide 3.3V to 25V input voltage range is ideal for systems that run on battery or AC-adapter power sources. The ISL62873 is a low-cost solution for applications requiring dynamically selected slew-rate controlled output voltages. The soft-start and dynamic setpoint slew-rates are capacitor programmed. Voltage identification logic-inputs select two resistor-programmed setpoint reference voltages that directly set the output voltage of the converter between 0.5V to 1.5V, and up to 3.3V using a feedback voltage divider. Optionally, an external reference such as the DAC output from a microcontroller, ...
