Automotive Grade TFT-LCD DC/DC with
Integrated Amplifiers
www.TdahteasIhSeLe7t48u0.2co0mand ISL78022 integrate a high performance
boost regulator with 2 LDO controllers for VON and VOFF, a
VON-slice circuit with adjustable delay and either one
(ISL78020) or five (ISL78022) amplifiers for VCOM and
VGAMMA applications.
The boost converter in the ISL78020 and ISL78022 is a
current mode PWM type integrating an 18V N-Channel
MOSFET. Operating at 1.2MHz, this boost converter can
operate in either P-Mode for superior transient response, or
in PI-Mode for tighter output regulation.
Using external low-cost transistors, the LDO controllers
provide tight regulation for VON, VOFF, as well as providing
start-up sequence control and fault protection.
The amplifiers are ideal for VCOM and VGAMMA
applications, with 150mA peak output current drive, 12MHz
bandwidth, and 12V/µs slew rate. All inputs and outputs are
rail-to-rail.
Available in a 32 Ld TQFP (7mmx7mm) Pb-free package, the
ISL78020, ISL78022 are specified for operation over a -40°C to
+105°C temperature range.
