MT7201C+ led driver datasheet, LED driver IC chip 6V~50V driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage up to 50V

MT7201C+ led driver datasheet, LED driver IC chip for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage up to 50V. The device operates from an input supply between 7~50V and provides an externally adjustable output current of up to 1A. Depending upon supply voltage and external components, this can provide up to 32 watts of output power. The MT7201 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.

The operation voltage range of MT7201C+ is different from MT7201C  LED driver datasheet

FEATURES
 Pass 4KV ESD test
 Simple low parts count
 1A output current
 Single pin on/off and brightness control using DC voltage or PWM
 Internal PWM filter
 Soft-start
 High efficiency (up to 97%)
 Wide input voltage range: 6V to 50V
 Output shutdown
 Up to 1MHz switching frequency
 Inherent open-circuit LED protection
 Typical 2% output current accuracy

Output current can be adjusted above, or
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.
