MCP1664T-E/MNY by Microchip Technology
High Voltage Output Boost LED Constant Current Regulator
| Status: | Active |
|---|---|
| Series: | MCP1664 |
| RoHS: | Compliant |
The device integrates a 36V, 400 mΩ low-side switch, which is protected by the 1.8A cycle-by-cycle inductor peak current limit operation. Low-voltage technology allows the MCP1664 to start-up without high inrush current or output overshoot. All compensation and protection circuitry is integrated to minimize the number of external components.
