DESCRIPTION
AMC7150 is a PWM power LED driver IC. The driving
current from few milliamps up to 1.5A. It allows high
brightness power LED operating at high efficiency from 4Vdc
to 40Vdc. Up to 200KHz external controlled operation
frequency. External resistor controlled the maximum output
current to single LED or a LED string.

Note :
Junction Temperature Calculation: TJ = TA + (PD x θJA).
PD: Power Dissipation, TA: Ambient temperature, θJA: Thermal Resistance-Junction to Ambient
The θJA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
