SNVS188I – MAY 2004 – REVISED OCTOBER 2017 LM2623 General-Purpose, Gated-Oscillator-Based DC-DC Boost Converter
1 Features 3 Description The LM2623 is a high-efficiency, general-purpose,
step-up DC-DC switching regulator for batterypowered and low input voltage systems. It accepts an
input voltage between 0.8 V and 14 V and converts it
into a regulated output voltage between 1.24 V and
14 V. Efficiencies up to 90% are achievable with the
LM2623. 1 Good Efficiency Over a Very Wide Load Range
