● Generates 15V at 45mA, –8V at 90mA from a Li-Ion Cell Output Disconnect Sequencing: Positive Output Reaches Regulation Before Negative Channel Begins Switching Internal Schottky Diodes 2MHz Constant Switching Frequency Requires Only One Resistor per Channel to Set Output Voltages VIN Range: 2.3V to 16V Output Voltage Up to 28V Short-Circuit Robust Capacitor Programmable Soft-Start Separate VBAT Pin Allows Separate Sources for Power and Control Circuitry Available in 10-Lead (3mm × 3mm) DFN Package The LT®3487 dual channel switching regulator generates positive and negative outputs for biasing CCD imagers. The device delivers up to –8V at 90mA and 15V at 45mA from a lithium-ion cell, providing bias for many popular CCD imagers. The boost regulator incorporates output disconnect technology to eliminate the DC current path from VIN to the output load that is present in standard boost configurations.
