MCP1662T-E/OT LED Driver ICs by Microchip Technology
High Voltage Output Boost LED Constant Current Regulator
| Status: | Active |
|---|---|
| Series: | MCP1662 |
| RoHS: | Compliant |
The device integrates a 36V, 800 mΩ low-side switch, which is protected by the 1.3A cycle-by-cycle inductor peak current limit operation. Low-voltage technology allows the MCP1662 to start-up without high inrush current or output overshoot. All compensation and protection circuitry is integrated to minimize the number of external components.
