1. APPLICABLE DEVICES
This specification document describes the SM8135BB/SM8135BB-G.
4-channel White LED Driver IC
2. OVERVIEW
The SM8135BB/SM8135BB-G are ×1.0/×1.5/×2.0 auto-switching charge pump boost DC/DC converter ICs. They have 4-channel LED drive current control circuits built-in, and can drive 1 to 4 white LEDs connected in parallel. The maximum LED drive current value for each channel is set using an external resistor.
