IS31FL3758 - 48CH LED DRIVER

Lumissil

Datasheet Details

S IS31FL3758 is a 48ch LED driver with 48 constant current channels.

It also supports from one to eight power scan to become a 48ch, 47×1, 46×2, 45×3…40×8, 40×9 matrix LED driver by control 9~2 external power PMOS.

Each channel can be pulse width modulated (PWM) with maximum 8-bit/6+2-bit 256 steps precision for smooth LED brightness control.

IS31FL3758 48CH LED DRIVER WITH 40×9 MATRIX EXTEND Preliminary Information May 2024.

Operating voltage: 2.7V to 5.5V.
Support 48 constant current channels @ 60mA/ch - ±7% bit-to-bit output current accuracy @IOUT=40mA, - ±6% device-to-device output current accuracy @IOUT=40mA - Combined for higher current capability with same current accuracy - Minimum headroom voltage of 200mV(typ. ) at 40mA.
Support to control the PMOS to become a matrix LED controller Support 48ch, 47×1, 46×2, 45×3, …, 40×8, 40×9, SW need external PMOS, OUT can control the SW timing.
