Rev 2.00
December 4, 2013 Automotive Grade TFT-LCD Power Supply
The ISL78010 is a multiple output regulator for use in all
TFT-LCD automotive applications. It features a single boost
converter with an integrated 2A FET, two positive LDOs for
VON and VLOGIC generation, and a single negative LDO for
VOFF generation. The boost converter can be programmed
to operate in either P-mode for optimal transient response or
PI-mode for improved load regulation. Features The ISL78010 includes fault protection for all four channels.
Once a fault is detected on either the VBOOST, VON or VOFF
channels, the device is latched off until the input supply or
EN is cycled. If a fault is detected on the VLOGIC channel,
the device is latched off until the input supply is cycled. The
VLOGIC channel is not affected by the EN function. VLOGIC-VBOOST-VOFF-VON or
VLOGIC-VOFF-VBOOST-VON sequence control The ISL78010 also includes an integrated start-up sequence
for VLOGIC, VBOOST, VOFF, then VON or for VLOGIC, VOFF,
VBOOST, and VON. The latter sequence requires a single
external transistor. The timing of the start-up sequence is set
using an external capacitor.
The ISL78010 comes in a 32 Ld 5x5 TQFP package and is
specified for operation over a -40В°C to +105В°C temperature …
