ZXLD1615Q
AUTOMOTIVE COMPLIANT HIGH LCD BIAS GENERATOR BOOST CONVERTER
Description
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.
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 60µA 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.
The device is assembled in a low profile TSOT25 package.
The ZXLD1615Q has been qualified to AEC-Q100 Grade 3 and is
Automotive Compliant supporting PPAPs.

See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free,
"Green" and Lead-free.
Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl)
and <1000ppm antimony compounds.
Automotive compliant products are AEC-Q100 qualified and are PPAP capable. Automotive, AEC-Q100 and standard products are electrically
and thermally the same, except where specified. For more information, please refer to
