FEATURES
DESCRIPTION
The LMZ31710 SIMPLE SWITCHER power module
2
Complete Integrated Power Solution Allows
is an easy-to-use integrated power solution that
Small Footprint, Low-Profile Design
combines a 10-A DC/DC converter with power
10mm x 10mm x 4.3mm Package
MOSFETs, a shielded inductor, and passives into a
- Pin Compatible with LMZ31707 & LMZ31704
low profile, QFN package. This total power solution
allows as few as three external components and
Efficiencies Up to 95%
eliminates the loop compensation and magnetics part
Eco-Mode / Light Load Efficiency (LLE)
selection process.
Wide-Output Voltage Adjust
The 10x10x4.3 mm QFN package is easy to solder
0.6 V to 5.5 V, with 1% Reference Accuracy
onto a printed circuit board and allows a compact
Supports Parallel Operation for Higher Current
point-of-load design. Achieves greater than 95%
Optional Split Power Rail allows
efficiency and excellent power dissipation capability
Input Voltage Down to 2.95 V
with
a
thermal
impedance
of
13.3°C/W.
The
LMZ31710 offers the flexibility and the feature-set of
Adjustable Switching Frequency
a discrete point-of-load design and is ideal for
(200 kHz to 1.2 MHz)
powering
a
wide
range
of
ICs
and
systems.
Synchronizes to an External Clock
Advanced packaging technology affords a robust and
Provides 180° Out-of-Phase Clock Signal
reliable power solution compatible with standard QFN
mounting and testing techniques.
Adjustable Slow-Start
Output Voltage Sequencing / Tracking
Figure 1. SIMPLIFIED APPLICATION
Power Good Output
Programmable Undervoltage Lockout (UVLO)
Over-Current & Over-Temperature Protection
Pre-bias Output Start-up
Operating Temperature Range: –40°C to 85°C
Enhanced Thermal Performance: 13.3°C/W
Meets EN55022 Class B Emissions
- Integrated Shielded Inductor
