MT7602

Features

MT7602 is a dual-channel linear constant current LED driver chip that can be used in various circuits that require constant current. It is especially optimized for LED applications. Its extremely low startup voltage can improve efficiency and reduce losses. When in use, only one external resistor is needed to set the current value of two channels at the same time, up to 30mA per channel. When a larger current is required, multiple channels can be connected in parallel to increase the output current capacity.

MT7602 can use VDD to implement PWM dimming function, thereby achieving dynamic dimming.

The extremely low operating voltage of MT7602 can realize self-bias application, that is, the VDD pin and VP pin are short-circuited to simplify the circuit connection.
