PAM2862应用电路
The PAM2862 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 and 30V and provides an externally adjustable output current of up to 1A. Depending upon supply voltage and external components, this can provide up to 24 watts of output power.
The PAM2862 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.
