LSP6501
1.6A, 1.3MHz, Boost DC-DC Converter
With Internal Switch
GENERAL DESCRIPTION
The LSP6501 is a current mode step up
converter that can carry out 1.6A. LSP6501 also
builds up a internal switch with 0.23 to provide a
high efficient regulator with fast response. The
LSP6501 can be operated at 640KHz or 1.3MHz
allowing for small filter solution and low noise. An
external
compensation
pin
gives
the
user
flexibility in setting up loop compensation, which
allows to use a low- ESR ceramic output
capacitors. Internal Soft-start function results in
small inrush current and the sofe-start can be
programmed with an external capacitor.
The LSP6501 device includes under-voltage
lockout, and current limiting protection preventing
damage in the event of an output overload. A low
profile 8-pin MSOP packages is available in the
LSP6501.
