Isolation capacitor picture

Isolated power is usually generated with a transformer, but it can also be generated using capacitors. For some systems, the constraints of size and cost may favor capacitors. In Figure 1, the IC (MAX256) is an …

What is a capacitive isolator?

e isolation barrier. A capacitive isolator’s inability to pass DC signals makes it inherently the right choice for isolation, which is why it is widely used in sensitive and important applications, such as telecom nd industrial power. Capacitive isolators are not susceptible to magnetic noise but can maintain high data rates and keep p

How does capacitive isolation work?

Capacitive isolation offers an easy solution to this. If the flyback control is generated at the secondary side, the controller can sense the turn-off of the synchronous rectifier (SR) and turn on the flyback quickly through the capacitive isolation link.

What is the difference between a capacitive isolator and an optocoupler?

Capacitive isolators are not susceptible to magnetic noise but can maintain high data rates and keep power consumption low. Capacitive isolation can also transfer signals bi-directionally, while optocouplers are unidirectional.

What are the benefits of capacitive isolation in adaptors?

The first benefit of capacitive isolation in adaptors is full secondary control of flyback converters. For USB power delivery quick chargers, manufacturers are expected to add much higher power to their existing adaptor portfolio, but still within a reasonably small size.

What is the difference between clearance and isolation capacitance?

Clearance – The shortest path between conductive input and output leads measured through air. Isolation Capacitance (CIO) – Total capacitance between the terminals on a first side connected together and the terminals on a second side of the isolation barrier connected together forming a 2-terminal device. Typical value is 1 or 2 pF.

Can capacitive isolation replace optocouplers in offline adaptors?

Capacitive isolation is a mature solution developed over the past decade to replace optocouplers in signal isolators, isolated gate drivers, isolated transceivers, and other applications1. However, the potential to use capacitive isolation to replace optocouplers in offline adaptors is often neglected.
