**AN920/D Theory and Applications of the MC34063** and A78S40 Switching Regulator Control **Circuits** This paper describes in detail the principle of operation of the MC34063 and μA78S40 switching regulator subsystems. Several converter design examples and numerous applications **circuits** with test data are included. INTRODUCTION

**OP-AMP COOKBOOK — Part 4**. By Ray Marston ... VOLTAGE REFERENCE **CIRCUITS**. An op-**amp** can be used as a fixed or variable voltage reference by wiring it as a voltage follower and applying a suitable reference to its **input**. An op-**amp** has a very high **input** impedance when used in the ‘follower’ mode and thus draws near-zero current from the ...

Note the two distinct regions of operation: one around Vi=0V, the linear region where the output changes linearly with respect to **input**, and the other at which changes in Vi has little affect on Vo, the saturation region (non-linear behavior). **Circuits** with **operational amplifiers** can be …

Question 3 Write the transfer function (**input**/output equation) for an operational amplifier with an open-loop voltage gain of 100,000, and the inverting **input** connected to a voltage divider on its output terminal (so the inverting **input** receives exactly one-half the output voltage). In other words, write an equation describing the output voltage of this op-**amp** (V out) for any given **input** ...

**Diode, rectifiers and power supplies** 6 Example 1 A 50 load resistance is connected across a half wave re ctifier. The **input** supply voltage is 230V (rms) at 50 Hz. Determine the DC output (average) voltage, **peak**-to-**peak** ripple in the output voltage (Vp-p), and the output ripple frequency (fr). Solution:

A **diode** is an electrical device allowing current to move through it in one direction with far greater ease than in the other. The most common kind of **diode** in modern circuit design is the semiconductor **diode**, although other **diode** technologies exist. Semiconductor diodes are symbolized in schematic ...

The **input** sensitivity as shown is 1.25V with VR1 at maximum - this means that the sensitivity is pretty close to perfect for a **nominal** 1V **input**. **LED** current is set to about 11mA with R3 at 1.2k but it is easily reduced if needed - if R3 is increased to 1.5k the **LED** current is just under 9mA.
