FN6501.1

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.

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.

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 -40°C to +105°C temperature range. It is both AEC-Q100 rated and fully TS16949 compliant.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability andresult in failures not covered by warranty.

NOTE:

4.ΘJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief for details.5.For ΘJC, the “case temp” location is taken at the package top center.

IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all testsare at the specified temperature and are pulsed tests, therefore: TJ = TC = TA.

Electrical Specifications

VDD = 5V, VBOOST = 11V, ILOAD = 200mA, VON = 15V, VOFF = -5V, VLOGIC = 2.5V, limits over -40°C to +105°C temperature range, unless otherwise specified. Boldface limits apply over the operating temperature range, -40°C to +105°C.
