Overview

MT7202 1.
5A LED driver with internal switch DESCRIPTION The MT7202 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage.
The device operates from an input supply between 6V~50V and provides an externally adjustable output current of up to 1.
5A.
The MT7202 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.
Output current can be adjusted below the set value, by applying an external control signal to the 'ADJ' pin.
The ADJ pin will accept either a DC voltage or a PWM waveform.
Depending upon the control frequency, this will provide either a continuous or a gated output current.
The PWM filter components are contained within the chip.
The PWM filter provides a soft-start feature by controlling the rise of input/output current.
The soft-start time can be increased using a...
