Product details

product description

JXC893XB is a high-precision non-isolated step-down LED constant current control chip. The chip works in critical inductor current mode and has a built-in OVP function. The Vovp voltage value can be set by adjusting the resistance of the external OVP resistor. It is suitable for 85VAC~265VAC Full voltage range non-isolated step-down LED lighting application.

The JXC893XB chip integrates a 500V power switch, adopts high-precision sampling, compensation circuits and high-voltage JFET power supply technology. It does not require VCC capacitors and startup resistors, nor any external compensation circuits and feedback circuits. The chip uses precise and stable adaptive technology. This makes the system peripherals very simple, can achieve high-precision LED constant current output and excellent line voltage adjustment rate under the condition of very few peripheral components, which greatly saves the system cost and volume. The JXC893XB chip works in the critical mode of inductor current, and the output current does not change with the change of inductance and LED operating voltage, so as to achieve excellent load regulation.

JXC893XB has multiple protection functions, including LED open/short circuit protection, chip power supply under-voltage protection, chip over-temperature adjustment, etc.
