APW7208 Description
The series connection allows the LED current to be identical for uniform brightness. Its low on-resistance of NFET and feedback voltage reduces power loss and achieves high efficiency. Fast 1MHz current-mode PWM operation is available for input and output capacitors and a small inductor while minimizing ripple on the input supply.
