JQC-3FF-S-Z relay datasheet

Description

JQC-3FF-S-Z relay is 10A, PCB Type, Form C Type. A relay allows a low-power electrical signal, such as from a microcontroller or sensor, to control a much larger current or voltage, such as required to drive a motor or light bulb. This allows a small electronic device to control a much larger one, or to isolate the low-power circuit from the high-power one. Relays are used in a wide range of applications, including automotive systems, HVAC systems, and computer power supplies.

Features

1. 10A switching capability

2. Small footprint

3. Sealed type available

4. Class B/F available

5. Conform to RoHS,ELV directive

BP2833A PDF Datasheet – Buck Offline LED Driver

Posted on by pinout

A Buck Offline LED Driver is a type of power supply or driver circuit designed to efficiently drive light-emitting diodes (LEDs) in various lighting applications. It operates on the buck (step-down) topology, which means it reduces the input voltage to a lower level suitable for driving LEDs. The “offline” designation indicates that it can operate directly from an AC mains power supply.

Part Number: BP2833A

Function: Non-isolated Buck Offline LED Driver

Package: SOP 8 Pin Type

Manufacturer: BPS ( www.bpsemi.com )

Description

The BP2833A is a high precision buck constant current LED driver. The device operates in critical conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting.

The BP2833A integrates a 500V power MOSFET. With patent pending MOSFET driving technique, the operating current of the IC is very low. So it doesn’t need the auxiliary winding for supplying the chip. It can achieve excellent constant current performance
with very few external components, so the system cost and size are minimized.

Features

1. Critical Conduction Mode Operation

2. Internal 500V Power MOSFET

3. No Auxiliary Winding

4. Ultra Low Operating Current

5. ±5% LED Output Current Accuracy

6. LED Open Protection
