3.16. MC34167

The MC34167, 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, under voltage lockout, and thermal shutdown. Also included is a
low power standby mode that reduces power supply current to 36mA.
• Output Switch Current in Excess of 5.0A
• Fixed Frequency Oscillator (72kHz) with On–Chip Timing
• Provides 5.05V Output without External Resistor Divider
• Precision 2% Reference
• 0% to 95% Output Duty Cycle
• Cycle–by–Cycle Current Limiting
• Under voltage Lockout with Hysteresis
• Internal Thermal Shutdown
• Operation from 7.5V to 40V
• Standby Mode Reduces Power Supply Current to 36mA
• Economical 5–Lead TO–220 Package with Two Optional Leadforms
• Also Available in Surface Mount D2PAK Package
• Moisture Sensitivity Level (MSL) Equals 1

3.17. TFMS5360

The TFMS5360 is a miniature receiver for infrared remote control systems.
• Photo detector and preamplifier in one.
• 36 KHZ
• Pin diode and preamp
• IR filter.
