I use the tps54550 power chip to generate 3.3V voltage. The waveform output from the PH end of the chip is correct, but after filtering, the output voltage is very low, only 0.005V. I use 6.8uH and 10...
We have a book selection on PADS/Altium Designer circuit design, and we are looking for authors who are interested in writing books. The author is required to have some practical experience and writin...
If there is no data, there is nothing to say. The above is the manual of the LCD on the board (to be precise, it is the LCD manual on the MSP-EXP5529 schematic diagram). In fact, the backlight circuit...

1 Overview
Drugs are like a "double-edged sword". They can treat diseases but can also cause serious adverse consequences. The dual nature of drugs depends on whether they are used rationally....[Details]
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[Details]
Magnetic resonance imaging (MRI) systems for medical and scientific applications require a high-performance, high-power inductor capable of establishing a uniform, strong magnetic field. Transverse el...[Details]

In the development of high-stability lasers, real-time monitoring of the working state of the laser is an issue that needs to be focused on. This system realizes the high-stability laser temperatur...[Details]
Adding "intelligence" to measurement systems is becoming more common as 8-bit microcontrollers are inexpensive, widely available, and can be programmed using today's common high-level languages, su...[Details]
To help improve DC/DC conversion efficiency at lighter loads and higher frequencies, Schottky diodes can be integrated into MOSFET chips to form a single package to reduce power dissipation in the ...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
introduction
Mobile phones, MP3 players, hard disk players, digital cameras, PDAs and other devices are all controlled by navigation keys. Currently, the more popular navigation key contro...[Details]
introduction
Controller Area Network (CAN) is a bus standard proposed by Bosch of Germany to solve the information communication between automotive electronic control units. With its excel...[Details]
Power semiconductors and reactive components (capacitors and inductors) are ubiquitous in today's electrical equipment. In normal operation, they can cause two undesirable side effects on the AC line ...[Details]
At present, TPMS (tire pressure monitoring system) is mainly divided into two types, one is indirect type and the other is direct type. The direct TPMS system has been affected by its poor alarm ac...[Details]
Abstract: By controlling the supply voltage of the radio frequency (RF) power amplifier (PA) in a CDMA/WCDMA cellular phone, the PA efficiency can be improved, heat generation can be reduced, and t...[Details]
