A single Dual Mode input provides a simple means of brightness adjustment and on/off control. Fast 1MHz current-mode PWM operation allows for small input and output capacitors and a small inductor while minimizing ripple on the input supply/battery. Soft-start eliminates inrush current during startup.
The MAX8595X/MAX8596X are available in a space-saving, 8-pin, 3mm x 3mm TDFN package.
