General Description
The IS32LT3126 is a dual linear programmable current regulator consisting of 2 independently controlled output channels; each channel is capable of sourcing 150mA.
Both channels can be combined to provide a total of 300mA.
It supports PWM dimming of both channels via power supply modulation (PSM).
Key Features
- ENx pins to individually PWM dim and independently adjust the average output current for each channel. The max current for each channel is set with its corresponding external resistor. The UVx pins set the VCC under voltage lockout of each channel to match the LED stack for high side PWM dimming operation. In addition, the IC integrates fault protection for LED open/short, ISETx pin open/short and over temperature condition for robust operation. Detection of these failures is reported by FAULTB.
