The data sheet introduces the STEVAL-ISA056V1 6 rows - 30 mA LEDs driver with boost converter for LCD panels backlight evaluation board, which is composed of the PM6600 controller, with a 4.5V to 28V input voltage range, internal Power MOSFET, internal +5V LDO for device supply, up to 36V output voltage, constant frequency peak current-mode control, 200kHz to 1MHz adjustable switching frequency, external synchronization for multi-device applications, pulse-skip power saving mode at light load, programmable soft-start, programmable OVP protection, single ceramic output capacitor, latched thermal shutdown.
The document describes the STEVAL-ISA056V1, an evaluation board based on the PM6600 chip. It is designed as a high-efficiency monolithic boost converter and controlled current generator specifically for supplying LED arrays in LCD panel backlights.
Key features include a boost section supporting 4.5 V to 28 V input voltage with up to 36 V output, an internal power MOSFET, and programmable soft-start. The backlight driver section supports six rows with a maximum current capability of 30 mA per row (adjustable), capable of driving up to 10 W LEDs per row.
The board accepts an input voltage ranging from 4.5 V to 28 V.
The device can manage an output voltage up to 36 V.
Each row has a maximum current capability of 30 mA.
