Description

The FR9886 is a synchronous step-down DC/DC converter that provides wide 4.5V to 23V input voltage range and 2.5A continuous load current capability. The FR9886 fault protection includes cycle-by-cycle current limit, input UVLO, output over voltage protection and thermal shutdown. Besides, adjustable soft-start function prevents inrush current at turn-on. This device uses current mode control scheme which provides fast transient response. Internal Compensation function reduces external compensation components and simplifies the design process. In shutdown mode, the supply current is less than 1uA. The FR9886 is available in an 8-pin SOIC package, provides a very compact system solution and good thermal conductance.

F12C20C rectifier diode

Description

F12C20C is 12A, 200V, Common Cathode Fast Recovery Rectifier Diode.

A fast recovery rectifier, also known as a fast recovery diode, is a semiconductor device used in electronic circuits to rectify alternating current (AC) into direct current (DC). These diodes are designed with the specific feature of having a fast recovery time, which means they can switch off quickly when the polarity of the voltage across them reverses.

1. Fast Recovery Time: The primary distinguishing feature of fast recovery rectifiers is their ability to switch from the conducting to non-conducting state (and vice versa) with minimal delay when the voltage polarity changes. This fast switching reduces reverse recovery losses, making them suitable for high-frequency and high-efficiency applications.

2. Low Reverse Recovery Charge: Fast recovery rectifiers are designed to have low reverse recovery charge (Qrr). This property reduces the energy dissipated during the switching transition, minimizing power loss and improving efficiency.
