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).
