The wide 3.3V to 25V input voltage range is ideal for systems that run on battery or ACadapter power sources. The ISL95875 and ISL95876 are lowcost solutions 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 four (ISL95875, ISL95876) resistor-programmed setpoint reference voltages that directly set the output voltage of the converter between 0.5V and 1.5V, and up to 5V with a feedback voltage divider. Compared with R3 modulator, t...
