### Using dual output LDO

No, you cannot connect the outputs of the AP7346D directly even if you only enable one at a time. They each have an internal discharge transistor that is enabled whenever the output is disabled, and ...

### Synchronous Buck Converter - PWM modulation

My question : Does the equation I used to calculate 5.5us only apply for no load conditions? When you have a synchronous buck regulator (as per your schematic), the duty cycle multiplied by the input ...

### Synchronous Buck Converter - PWM modulation

The equation applies for no-resistance condition and instantaneous switching. Include Rds(on), inductor ESR, and capacitor or supply impedances, and you will see it needs slightly more under load. ...

### Questions regarding analog compensator

As shown, this integrates DC error to null average for steady state. Yet Type II compensation with voltage FB only has poor step response since there is latency in the error voltage. Thus the metrics ...

The essence of the LQR-based feedback controller is to place the pole of the dynamical matrix to the LHS plane, so that your closed-loop system $\dot{x}=(A-BK)x$ will be stable. But $x$ here doesn'...

### PID control with anti-windup time specifications

It appears that that more complicated form of anti-windup measure based on kt complicates matters in terms of tuning the PID controller and obtaining the values for kp, ki and kd. I don't think that ...

### Using dual output LDO

What you can do is to Power-OR them: simulate this circuit – Schematic created using CircuitLab When OUT1_en is high and OUT2_en is low the combined output will come from OUT1 only. Likewise, ...
