DESCRIPTION

The MT7201C 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~40V and provides an

externally adjustable output current of up to

1A.

The MT7201C 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 an

external capacitor from the ADJ pin to ground.

Applying a voltage of 0.2V or lower to the ADJ

pin turns the output off and switches the

device into a low current standby state.

The device is assembled in a SOT89-5 pin

package.
