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.

Quiescent current is typically 60A and a shutdown function is
provided to reduce this current to less.
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.
