FEATURES
DESCRIPTION
Complete Integrated Power Solution Allows
The LMZ34002 SIMPLE SWITCHER® power module
Small Footprint, Low-Profile Design
is an easy-to-use, negative output voltage power
Wide Input Voltage Range from 4.5 V to 40 V
module that combines a 15-W DC/DC converter with
Output Adjustable from –3.0 V to –17 V
a shielded inductor, and passives into a low profile,
QFN package. This total power solution allows as few
Supplies up to 2-A of Output Current
as five external components and eliminates the loop
45-V Surge Capability
compensation and magnetics part selection process.
Synchronizes to an External Clock
The 9x11x2.8 mm QFN package is easy to solder
Adjustable Slow-Start
onto a printed circuit board and allows a compact
Programmable Undervoltage Lockout (UVLO)
design with fewer components and excellent power
dissipation capability. The LMZ34002 offers the
Output Overcurrent Protection
flexibility and the feature-set of a discrete design and
Over Temperature Protection
is ideal for powering a wide range of ICs and analog
Operating Temperature Range: –40°C to 85°C
circuits requiring a negative output voltage. Advanced
packaging technology affords a robust and reliable
Enhanced Thermal Performance: 14°C/W
power
solution

High Density Power Systems
Safe Operating Current
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
