| Manufacturer | Lumissil |
| Description | The IS32LT3965 is a synchronous DC/DC switching LED driver that integrates high-side and low-side Nchannel MOSFETs to operate in a Buck configuration. The device can operate from a wide input voltage between 3.8V and 38V and provides a constant current of up to 1.5A for driving a single LED or multiple series connected LEDs. The external resistor, RIS, is us. |
| Features |
• Wide input voltage supply from 3.8V to 38V • High-side sense and true average output current control, up to 1.5A maximum over temperature range • Operating frequency up to 2.2MHz • Forced Continuous Conduction Mode (FCCM) operation • Integrated high-side and low-side MOSFET switches • Cycle-by-cycle current limit • Dimming via PWM logic input or analog voltage - Supports LED thermal roll-off or LED binning • Internal control loop compensation • Externally programmable undervoltage lockout (UVLO) • 1μA low power shutdown • Spread spectrum to optimize EMI • Robust fault protection and reportin. |
