I use an ST7 RC oscillator and an auto-reload timer. When the PLL is disabled, the frequency is very accurate and is set to 4ms. When the multiplier 8 PLL is enabled at 5V, the clock is much worse and...
When designing a multi-stage high-gain circuit, its stability index, noise index, bandwidth index, etc. are all different from those of a single stage. For multi-stage amplifiers, especially high gain...
The figure below is a boost circuit that requires an input of 5V and outputs 15V.
After the circuit was soldered, the 34063 was burned out as soon as it was powered on. It was very hot and no short ci...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
