High-Efficiency, 36V Step-Up Converters
with T A Derating Option for 2 to 9 White LEDs
General Description
The MAX8595X/MAX8596X drive up to nine white LEDs
with constant current and high efficiency to provide
LCD backlighting in cell phones, PDAs, and other
handheld devices. The series connection allows the
LED currents to be identical for uniform brightness and
minimizes the number of traces to the LEDs. The
MAX8595X regulates constant LED current over the
entire temperature range. The MAX8596X features an
ambient-temperature derating function to avoid over-
driving the white LEDs during high ambient tempera-
tures, enabling higher drive current below +42°C.
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.
