Features
3 Description
The LMZ20502 SIMPLE SWITCHER® Nano Module
1
Integrated Inductor
regulator is an easy-to-use synchronous step-down
Miniature 3.5 mm x 3.5 mm x 1.75 mm Package
DC-DC converter capable of driving up to 2 A of load
2 A Maximum Load Current
from an input of up to 5.5 V, with exceptional
efficiency and output accuracy in a very small
Input Voltage Range of 2.7 V to 5.5 V
solution size. The innovative package contains the
Adjustable Output Voltage Range of 0.8 V to 3.6 V
regulator and inductor in a small 3.5 mm x 3.5 mm x
± 1% Feedback Tolerance Over Temperature
1.75 mm volume, thus saving board space and
eliminating
the
time
and
expense
of
inductor
2.4 µA (max) Quiescent Current In Shutdown
selection. The LMZ20502 requires only five external
3 MHz Fixed PWM Switching Frequency
components and has a pin-out designed for simple,
-40°C to 125°C Junction Temperature Range
optimum PCB layout. The LMZ20502 is a member of
Power Good Flag Function
Texas Instruments' SIMPLE SWITCHER family. The
SIMPLE SWITCHER concept provides for an easy to
Pin-Selectable Switching Modes
use complete design with a minimum number of
Internal Compensation and Soft-Start
external components and the TI WEBENCH® design
Current Limit, Thermal Shutdown, and UVLO
tool. TI's WEBENCH tool includes features such as
Protection
external component calculation, electrical simulation,
and WebTherm™. For soldering information, please
refer to the following document: SNOA401.
