Allegro Microsystems Announces Multi-Output Regulators for Automotive LCD Display

Allegro Microsystems, LLC announces a new multi-output regulator that complies with the AEC-Q100 standard. This regulator is suitable for power supply for automotive LCD displays. The Allegro A8603 operates with a fixed switching frequency, and 350 kHz to 2.25 MHz fixed switching frequencies can be synchronized by programming or external clock signals. This minimizes interference with AM and FM bands. With I2CTM compatible serial interface, the system microcontroller can configure A8603 by writing its internal registers. If a fault occurs, the system controller can also access the A8603 status register. Allegro Microsystems Announces Multi-Output Regulators for Automotive LCD Display The A8603 integrates a boost stage, which is followed by two linear regulators and two charge pump regulators. Each output voltage can be independently programmed through the I2CTM serial interface. During power-up and closing, the output can be turned on and turned off in the pre-program order (with adjustable delay). This allows the user to meet the order requirements of a particular LCD panel. All outputs have short circuit protection. The internal boost switch has an overcurrent and overvoltage protection. The A8603 is available in a 24-pin, 4 × 4 mm QFN package. The device is equipped with a bare radiator to operate at a high ambient temperature, and is a lead-free (PB) package, and the pin frame is 100% fog tin electroplating.
