Application Notes:

The MCP1664 device is a compact, space-efficient, fixed-frequency, non-synchronous step-up converter optimized to drive LED strings with constant current from two and three-cell alkaline and NiMH/NiCd or one-cell Li-Ion or Li-Polymer batteries.
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.

  • Up to 92% Efficiency
  • High Output Voltage Range: up to 32V
  • ILEDup to 300 mA @ 5.0V VIN, 4 White LEDs
  • ILED up to 200 mA @ 3.3V VIN, 4 White LEDs
  • ILED up to 150 mA @ 4.2V VIN, 8 White LEDs
  • Input Voltage Range: 2.4V to 5.5V
  • UVLO@VIN Rising:  2.3V, typical
  • UVLO@VIN Falling: 1.85, typical
  • No Load Input Current: 250 µA, typical
  • Sleep mode with 200 nA Typical Quiescent Current
  • PWM Operation with Skip mode: 500 kHz
  • Feedback Voltage Reference: VFB= 300 mV
  • Cycle-by-Cycle Current Limiting
  • Internal Compensation
  • Inrush Current Limiting and Internal Soft-Start
  • Feedback Pin Shorted to GND (Prevent Excessive Current into LEDs)
  • Disconnected LED String (Prevent Overvoltage to the Converter’s Output and SW Pin)
  • Overtemperature Protection 
  • Available Packages: 5-Lead SOT-23 or 2x3 8-Lead TDFN
