ZXLD1615QET5TA

ZXLD1615Q AUTOMOTIVE COMPLIANT LCD BIAS GENERATOR BOOST CONVERTER Description Pin Assignments The ZXLD1615Q is a PFM inductive-boost-converter designed to provide output voltages of up to 28V from a 2.5V to 5.5V input supply. TSOT25 The ZXLD1615Q includes the output switch and peak current sense resistor, and can provide up to 10mA output current at maximum output voltage. Higher current is available at lower output voltages. LX 1 Quiescent current is typically 60A and a shutdown function is provided to reduce this current to less. GND 2 FB 3 Nominal output voltage can be set up to a maximum of 28V by two external resistors and can be adjusted to lower values by a PWM control signal applied to the 'Enable' pin. Depending upon the control frequency, the PWM signal will provide either continuous (low ripple) or gated control. The PWM filter components are contained within the chip. Minimum output voltage is determined by the input supply.
