DESCRIPTION

•

Enhanced Product-Change Notification

The TPS54350 is

medium output current

(1)

Qualification Pedigree

synchronous buck PWM converter with an integrated

high side MOSFET and a gate driver for an optional

low side external MOSFET. Features include a high

performance voltage error amplifier that enables

maximum performance under transient conditions

and flexibility in choosing the output filter inductors

100 mW, 4.5-A Peak MOSFET Switch for High

Efficiency at 3-A Continuous Output Current

•

Uses External Lowside MOSFET or Diode

Output Voltage Adjustable Down to 0.891 V

With 2% Accuracy

and

capacitors.

The

TPS54350

has

•

Synchronizes to External Clock

under-voltage-lockout circuit to prevent start-up until

the input voltage reaches 4.5 V; an internal slow-start

circuit to limit in-rush currents; and a power good

output to indicate valid output conditions. The

synchronization feature is configurable as either an

input or an output for easy 180° out of phase

synchronization.

180° Out of Phase Synchronization

Wide PWM Frequency – Fixed 250 kHz,

500 kHz or Adjustable 250 kHz to 700 kHz

•

Internal Slow Start

Load Protected by Peak Current Limit and

Thermal Shutdown

The TPS54350 device is available in a thermally

enhanced 16-pin TSSOP (PWP) PowerPAD™

package. Texas Instruments provides evaluation

modules and the SWIFT™ designer software tool to

aid in quickly achieving high-performance power

supply designs to meet aggressive equipment

development cycles.

16-Pin TSSOP PowerPAD™ Package

(1) Component qualification in accordance with JEDEC and

industry standards to ensure reliable operation over an

extended temperature range. This includes, but is not limited

to, Highly Accelerated Stress Test (HAST) or biased 85/85,

temperature cycle, autoclave or unbiased HAST,

electromigration, bond intermetallic life, and mold compound

life. Such qualification testing should not be viewed as

justifying use of this component beyond specified

performance and environmental limits.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
