BL8532 can drive 32 LEDs

BL8532 is a switching DC/DC step-up constant current chip suitable for LED driving in PFM control mode. The output current can be kept constant at 0-500mA by adjusting the external resistor. BL8532 can provide constant current power to multiple LEDs through multiple parallel connections or multiple parallel and two

Summary of LED driving technology

Driver Classification According to the current polarity of the LED driver power supply output, the LED drive mode can be divided into DC drive and AC drive. DC drive is mainly for DC LEDs, and the load only flows current in one direction, while AC drive is mainly for AC LEDs, and the load flows current in both direct

Which conversion method should LED driver choose?

What kind of conversion method Converting voltages using linear regulators will face power consumption issues, so this method is more suitable for conversion circuits that need to avoid noise (such as car audio) and therefore cannot use switching methods. The switching method is characterized by very high c

Preventing the driver power supply from "falling off the chain" - Analysis of LED lighting test technology

LED lighting has the characteristics of energy saving, environmental protection, long life, easy control, and maintenance-free. However, ironically, we often hear that the life of LED driving power directly drags down the LED lighting fixtures and makes them not "long-lived", which greatly increases the maintenance/use

Precautions for using chip capacitors in LED drive circuits

The full name of chip capacitors is multilayer (laminated, stacked) chip ceramic capacitors, abbreviated as MLCC. When MLCC is subjected to temperature shock, cracks are likely to occur from the soldering end. In this regard, small-sized capacitors are relatively better than large-sized capacitors. The principle i

White LED Driver with High Temperature Protection

The circuit drives a high-power white LED (WLED) and turns off the LED when the temperature is too high and the thermistor fails in an open or short circuit.

Overview of linear LED driver solutions and their typical application cases

In many lighting applications, linear LED drivers are the preferred solution because they are relatively simple, easy to design, and enable LEDs to be driven with a precise regulated current regardless of changes in the LED forward voltage drop or input voltage. Since the drivers are linear structures,
