Xl4001 / xl4002 car charging scheme 2.1 A car charger IC CX8505

Combined with the high pressure and BCD high suppression process xl4001, xl4002, xl4101, xl4102 products, the input voltage can be 5v - 40v, with constant current, constant pressure function, built-in overpressure, overflow, short circuit and overtemperature protection.For the market application of led drive and mr16 drive (1w / 3w led up to 10 series), the peripheral circuit is simple and stable.Constant current source output, maximum current can do 3a.Fixed switch frequency of 52khz. When the input/output voltage changes, the range of load current varies within plus or minus 1%.

When multiple leds are connected, the efficiency can reach 96% of the temperature protection (120 degrees Celsius).

Xl4001 (1w / 3w led up to 10 series) chip features:

* 5-40v input voltage range (limit voltage 50v)

* the output current of Max 2a

* built-in power mosfet has constant current, constant pressure function, built-in overpressure, overcurrent, short circuit and overtemperature protection

* 152khz fixed switch frequency

* when the input/output voltage changes, the load current varies in the range of plus or minus 1 percent.

* when multiple leds are connected, the efficiency can be up to 96%.

* overtemperature protection (120c)

* high temperature start - 20 ~ 85 degrees Celsius

* the over-current of each cycle protects the mr16 spotlights and led illuminates
