MC34166 POWER SWITCHING REGULATORS

of each section of the device is given below with the representative block diagram shown in Figure 13. Oscillator The oscillator frequency is internally programmed to 72 kHz by capacitor CT and a trimmed current source. The charge to discharge ratio is controlled to yield a 95% maximum duty cycle at.

Order this document by MC34166/D Power Switching Regulators The MC34166, MC33166 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 o.
