Features & Applications

MCP1650 series of 750 kHz gated oscillator boost controller packaged in an 8 or 10-pin MSOP package. Developed for high-power, portable applica-tions, the gated oscillator controller can deliver 5 watts of power to the load while consuming only 120 µA of quiescent current at no load.

MCP1650/51/52/53 can operate over a wide input voltage range (2.0 V to 5.5 V) to accommodate multiple primary-cell and single-cell Li-Ion battery-powered applications, in addition to 2.8 V, 3.3 V and 5.0 V regulated input voltages. Additional features integrated on the MCP1650/51/52/ 53 family include peak input current limit, adjustable output voltage/current, low battery detection and power-good indication.

Features:

  • Output Power Capability Over 5 Watts
  • 560/440 Output Current (mA)
  • Output Voltage Capability From 3.3 V to Over 100 V
  • 750 kHz Gated Oscillator Switching Frequency
  • Adaptable Duty Cycle for Battery or Wide-Input, Voltage-Range Applications
  • Input Voltage Range: 2.0 V to 5.5 V
  • Capable of SEPIC® and Flyback Topologies
  • Shutdown Control with IQ < 0.1 µA (Typical)
  • Low Operating Quiescent Current: IQ = 120 µA
  • Voltage Feedback Tolerance (0.6%, Typical)
  • Popular MSOP-8 Package
  • Peak Current Limit Feature
  • Two Undervoltage Lockout (UVLO) Options:
    • 2.0 V or 2.55 V
  • Operating Temperature Range: -40°C to +125°C

Applications:

  • High-Power Boost Applications
  • High-Voltage Bias Supplies
  • White LED Drivers and Flashlights
  • Local 3.3 V to 5.0 V Supplies
  • Local 3.3 V to 12 V Supplies
