The LT1610 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 VC pin, eliminating two external components. No-load quiescent current of the LT1610 is 30µA, 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.
The LT1610 is a micropower step‑up DC‑DC converter designed for low‑power applications such as pagers, cordless phones, and battery‑backed LCD bias circuits. It operates from a single cell as low as 0.9 V, uses a 1.7 MHz fixed switching frequency, and achieves high efficiency with an automatic burst‑mode at light loads.
Typical applications include SEPIC converters, boost converters, and other portable electronic circuits. The datasheet provides pin descriptions, layout recommendations, component selection guidelines, and package dimensions for the 8‑lead MSOP and SO variants.
