The LTC3422EDD#TRPBF is a high-efficiency, current mode, fixed-frequency, step-up DC/DC converter designed for portable applications. It offers true output disconnect and inrush current limiting capabilities.
Key electrical specifications include an input voltage range of 0.5V to 4.5V and an adjustable output voltage range from 2.25V to 5.25V. The device features a 1.5A switch current limit, with typical NMOS and PMOS switch on-resistances of 0.20Ω and 0.24Ω respectively. It operates with a low quiescent current of 25µA in Burst Mode and a shutdown current of less than 1µA.
This converter supports a maximum switching frequency of 3MHz and guarantees start-up from as low as 0.88V (typically 1V). It is housed in a compact, thermally enhanced 10-pin DFN package measuring 3mm x 3mm x 0.75mm.
Applications for the LTC3422EDD#TRPBF include wireless handsets, handheld computers, GPS receivers, and MP3 players, where efficient power conversion from low input voltages is critical.
The input voltage range is 0.5V to 4.5V.
The output voltage can be adjusted from 2.25V to 5.25V.
The switch current limit is 1.5A.
The quiescent current in Burst Mode is typically 25µA.
It is supplied in a 10-WFDFN exposed pad package, measuring 3mm x 3mm x 0.75mm.
The maximum switching frequency is 3MHz.
