产品概述
The MCP1662T-E/OT is a high-voltage step-up LED Driver with UVLO and open load protection. The MCP1662 device is a compact, space-efficient, fixed-frequency, non-synchronous step-up converter optimized to drive LED strings with constant current from a two- or three-cell alkaline or lithium Energizer® or NiMH/NiCd or one-cell Lithium-Ion or Li-polymer batteries. The device integrates a 36V, 800mR low-side switch, which is protected by the 1.3A cycle-by-cycle inductor peak current limit operation. All compensation and protection circuitry is integrated to minimize the number of external components. The internal feedback (VFB) voltage is set to 300mV for low power dissipation when sensing and regulating the LED current. A single resistor sets the LED current.
- 36V, 800mR Integrated switch
- Up to 92% efficiency
- Drive LED strings in constant current
- 1.3A Peak input current limit
- VFB = 300mV Feedback voltage reference
- Under-voltage lockout (UVLO)
- Sleep mode with 20nA typical quiescent current
- Cycle-by-cycle current limiting
- Internal compensation
- Open load protection (OLP) in the event of feedback pin shorted to GND
- Over-temperature protection
