Overview

The MC34166, MC33166 series are high performance fixed frequency power switching regulators that contain the primary functions required for dc-dc converters. This series was specifically designed to be incorporated in buck, boost and inverting applications with a minimum number of external components and can also be used cost effectively in step-up applications.

These Buck Boost Inverting Switching Regulators 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 mA.

  • Output Switch Current in Excess of 3.0 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

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
