BP1362 is an LED constant current driver chip with enable control, suitable for step-down non-isolated applications. BP1362 operates in continuous conduction mode of inductive current. Compared with discontinuous conduction mode, it has smaller peak current and smaller effective current, so the device loss is lower and the system can have higher efficiency. BP1362 adopts advanced output constant current technology to ensure that the output current does not change with the inductance and the operating voltage of the LED. BP1362 integrates input start-up and power supply functions, without the need for a start-up resistor or a power supply winding. BP1362 also integrates perfect protection functions, including cycle-by-cycle overcurrent protection of input current, open circuit protection of current detection pins, and output current over-temperature regulation function.
