advertisement Tiny Versatile Buck Regulators Operate from 3.6V to 36V Input
Design Note 367
Hua (Walker) Bai
Introduction
Linear Technology offers two new buck regulators that
operate from a wide input voltage range (3.6V to 36V)
and take so little space that they easily solve many difп¬Ѓcult power supply problems. The LTВ®1936 and LT1933
are perfect for applications with disparate power inputs
or wide range input power supplies such as automotive
batteries, 24V industrial supplies, 5V logic supplies
and various wall adapters. Both parts are monolithic
current mode PWM regulators which provide excellent
line and load regulation and dynamic response. They
operate at a 500kHz switching frequency, enabling the
use of small, low cost inductors and ceramic capacitors,
resulting in low, predictable output ripple.
Small Size and Versatility
The LT1936 regulator includes a 1.9A power switch in
a tiny, thermally enhanced 8-lead MSOP. The LT1933
regulator includes an internal 0.75A power switch in a
tiny 6-lead ThinSOTв„ў package, which occupies less than
0.15in2 board space. The LT1936 offers the option of
external compensation for design п¬‚exibility or internal …
