General Description<\/h3>\n\n\n\n

The ECT6322M is a continuous mode inductive step-down converter, designed for driving single or multiple series
connected LEDs efficiently from a voltage source higher than voltage and external components, this can provide up to 42 watts of output power.<\/p>\n\n\n\n

The ECT6322M includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Depending upon the control frequency, this will provide either a continuous or a gated output current.<\/p>\n\n\n\n

The PWM filter components are contained within the chip. The ECT6322M is available in SOT-23 and SOP-8 Lead-free package.<\/p>\n\n\n\n
