Features & Applications

The MC33167 series are high performance fixed frequency power switching regulators that contain the primary functions required for dc−to−dc converters. This series was specifically designed to be incorporated in step−down and voltage−inverting configurations with a minimum number of external components and can also be used cost effectively in step−up applications.

These devices consist of an internal temperature compensated reference, fixed frequency oscillator with on−chip timing components, latching pulse width modulator for single pulse metering, high gain error amplifier, and a high current output switch. Protective features consist of cycle−by−cycle current limiting, undervoltage lockout, and thermal shutdown. Also included is a low power standby mode that reduces power supply current to 36 µA.

Key Features:

  • Output Switch Current in Excess of 5.0 A
  • Fixed Frequency Oscillator (72 kHz) with On−Chip Timing
  • Provides 5.05 V Output without External Resistor Divider
  • Precision 2% Reference
  • 0% to 95% Output Duty Cycle
  • Cycle−by−Cycle Current Limiting
  • Undervoltage Lockout with Hysteresis
  • Internal Thermal Shutdown
  • Operation from 7.5 V to 40 V
  • Standby Mode Reduces Power Supply Current to 36 µA
  • Economical 5−Lead TO−220 Package with Two Optional Leadforms
  • Also Available in Surface Mount D2PAK Package
  • Moisture Sensitivity Level (MSL) Equals 1
  • Pb−Free Packages are Available

Applications:

  • Digital TV (LCD, PDP)
  • Efficient system pre-regulator for linear voltage regulators
  • Battery chargers
