INFORMACIJE O IZDELKU
Pregled izdelka
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, 800mΩ 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.
