Offline and DC-DC PWM Controllers for
High-Brightness LED Drivers
Application Circuits
Figure 5 shows an offline application of an HB LED dri-
ver using the MAX16801. The use of transformer T1
allows significant design flexibility. Use the internal
error amplifier for a very accurate LED current control.
Figure 6 shows a discontinuous flyback LED driver with
linear dimming capability. The total LED voltage can be
lower or higher than the input voltage.
Figure 7 shows a continuous-conduction-mode HB LED
buck driver with linear dimming and just a few external
components.
Figure 8 shows an offline isolated flyback HB LED dri-
ver with low-frequency PWM using MAX16801. The
PWM signal needs to be inverted (see the Functional
Diagram ). Transformer T1 provides full safety isolation
and operation from universal AC line (85VAC to
265VAC).
