  • D/A Conversion Using PWM and R-2R Ladders to Generate Sine and DTMF Waveforms
    . PWM_Freq. = (Sine_freq) • (# of steps) • 10. = 60 • 32 • 10. Many embedded applications require the generation of. = 19.2 kHz. analog signals. Although separate D/A converter IC’s. exist on the market today, their extra price makes them. A simple RC low pass filter is the only external compo
  • Protection For Switching Regulators
    , thus increasing the efficiency of the regulator. D1 provides a momentary path for the current through LO, RL and is used only during the switch-over time of Q1 turning off and Q2 turning on generated by the PWM. Even though most synchronous PWM IC's provide control and monitoring signals, they do
  • DC/DC Converters In Power Sequencing Systems
    , as well as, for different input voltage ranges within a family. The follow up design tip may provide some assistance to system engineers. Figure 1 shows the block diagram of a flyback converter with the bias circuitry for the control IC (PWM) and the feedback loop consistent of the error OPAM A1
  • What Is So Great About Synchronous Rectification?
    to both Figures 1A & 1B, at t0 the PWM turns Q1 off. The current through Q1 drops to zero and causes the magnetic field in T1 to collapse and the drain to source voltage of Q1 to rise. Due to the parasitic capacitance of Q1 and the reflected gate to source capacitor of Q2 and the externally installed
  • Temperature Measurement Circuits for Embedded Applications
    will be compared with a frequency output RTD oscillator circuit, along with design examples using serial and analog output silicon Integrated Circuit (IC) sensors. In addition, a Programmable Gain Amplifier (PGA) circuit will be shown that can increase the effectiveness of the Analog-to-Digital Converter (ADC) bit
  • Sensorless Field Oriented Control of PMSM Motors using dsPIC30F or dsPIC33F Digital Signal Controllers
    environmental demands. they incorporate peripherals that are ideally suited for motor control, such as: This application note discusses implementation of a sensorless FOC algorithm for Permanent Magnet Syn- * Pulse-Width Modulation (PWM) (R) chronous Motors (PMSMs) using the Microchip dsPIC * Analog
  • Dealing With Noise Generated By A DC/DC Converter
    each other. Cost reduction efforts have influenced the industry up to a point that IC and converter manufacturers design application-specific products to minimize cost. The most commonly used noise reduction component is a low-pass filter at the output and/or input. Noise in DC/DC converters
