DESIGN IDEAS Versatile LTC3830 and LTC3832 Deliver
High Efficiency for Step-Down, Step-Up
and Inverting Power Conversions
by Wei Chen and Charlie Zhao
Introduction
The LTC3830 and the LTC3832 are
pin-to-pin compatible upgrades to the
LTC1430вЂ”a popular IC for low voltage step-down applications due to its
simplicity and high efficiency. The
LTC3830 and the LTC3832 remove
the LTC1430вЂ™s frequency foldback at
startup, thus eliminating inrush current and resulting output overshoot.
Other improvements over the
LTC1430 include tighter gm distribu-+
