The LT ? 1610 is a micropower fixed frequency DC/DC
converter that operates from an input voltage as low as 1V.
Intended for small, low power applications, it switches at
1.7MHz, allowing the use of tiny capacitors and inductors.
The device can generate 3V at 30mA from a single cell
(1V) supply. An internal compensation network can be
connected to the LT1610’s V C pin, eliminating two exter-
nal components. No-load quiescent current of the LT1610
is 30 μ A, and the internal NPN power switch handles a
300mA current with a voltage drop of 300mV.
The LT1610 is available in 8-lead MSOP and SO packages.
