IT 1602 -
2A, 24V, 310KHz Async. Step-Down LED Driver
Description
IT1602 is a PWM step-down converter designed to meet maximum 2A constant current for high power LED driving application, with a fixed switching frequency of 310kHz and a wide input supply range of 3.6V~24V. The 0.25V low feedback voltage reduces the power dissipation of the constant current setting resistor so that the high conversion efficiency up to 94% can be achieved. Moreover, a built-in low RDS(ON) power PMOSFET is also included to obtain a low conduction loss under heavy load conditions.
Not only providing excellent line/load regulations, IT1602 also features other functions, such as: external ON/OFF control, cycle-by-cycle current limit, and thermal shutdown protection. With the maximum duty cycle of 100%, IT1602 is also suitable for low drop-out conditions. This device is available in standard SOP-8L package.
