LM3102, LM3102-Q1

SNVS515H –SEPTEMBER 2007–REVISED JUNE 2015

LM3102/-Q1 SIMPLE SWITCHER Synchronous 1-MHz, 2.5-A

Step-Down Voltage Regulator

1 Features

•

Storage Systems

Broadband Infrastructure

•

LM3102-Q1 is an Automotive-Grade Product that

is AEC-Q100 Grade 1 Qualified (–40°C to +125°C

Operating Junction Temperature)

Direct Conversion from 2-, 3-, and 4-Cell Lithium

Batteries Systems

•

Low Component Count and Small Solution Size

Stable With Ceramic and Other Low-ESR

Capacitors

The

LM3102/-Q1

SIMPLE

SWTCHER^®

Synchronously Rectified Buck Converter features all

required functions to implement a highly efficient and

cost-effective buck regulator. The device can supply

2.5 A to loads with an output voltage as low as 0.8 V.

Dual N-channel synchronous MOSFET switches

allow

low component count, thus reducing

complexity and minimizing board size.

Programmable Switching Frequency up to 1 MHz

Valley Current Limit

Different from most other COT regulators, the

LM3102/-Q1 does not rely on output capacitor ESR

for stability, and is designed to work exceptionally

well with ceramic and other very low-ESR output

response and simple circuit implementation. The

operating frequency remains nearly constant with line

variations due to the inverse relationship between the

input voltage and the ON-time. The operating

frequency can be externally programmed up to

1 MHz. Protection features include V_CCundervoltage

lockout (UVLO), output overvoltage protection,

thermal shutdown, and gate drive UVLO. The

LM3102/-Q1 is available in the thermally enhanced

HTSSOP-20 package, and LM3102 is also available

in a DSBGA low-profile chip-scale package with

reduced output current.
