Integrated 8-Channel LED Driver with
Switch-Mode Boost and SEPIC Controller
Computing Power Dissipation
Use the following equation to estimate the upper limit
power dissipation (PD) for the MAX16807:
PCB Layout Guidelines
Careful PCB layout is critical to achieve low switching
losses and clean, stable operation. Use a multilayer
board whenever possible for better noise immunity.
?
PD = DUTY x ? ( V + x I + ) +
? ?
i = 7 ?
∑ V OUTi x I OUTi ? + ( V CC x I CC )
?
i = 0 ?
Protect sensitive analog grounds by using a star
ground configuration. Minimize ground noise by con-
necting AGND, PGND, the input bypass-capacitor
where:
V+ = supply voltage
I+ = operating supply current
DUTY = PWM duty cycle applied to OE
V OUTi = MAX16807 port output voltage when driving
load LED(s)
I OUTi = LED drive current programmed by R SET
PD = power dissipation.
Pin Configuration
ground lead, and the output-filter ground lead to a sin-
gle point (star ground configuration). Also, minimize
trace lengths to reduce stray capacitance, trace resis-
tance, and radiated noise. The trace between the out-
put voltage-divider and the FB pin must be kept short,
as well as the trace between AGND and PGND.
