Figure 1 shows the LT1935 generating
5V. Maximum load with VIN = 3.3V is
1A; from 2.5V the maximum load is
600mA. Note that the circuit efп¬Ѓciency D1 SW R1

SHDN The small size eases system design
in many applications. Large digital
systems with dense layouts often
need point-of-load converters to generate secondary logic supplies. With
a minimum input voltage of 2.3V, the
LT1935 can convert power from 2.5V,
3.3V or 5V logic rails to a higher output
voltage. Even handheld electronics
such as cell phones, digital cameras
and music players require peak power
levels of several watts to drive LEDs, …
