FEATURES

DESCRIPTION

Low Voltage Separate Power Bus

15-mΩ MOSFET Switches for High Efficiency

at 9-A Continuous Output

Adjustable Output Voltage

Externally Compensated With 1% Internal

Reference Accuracy

Fast Transient Response

Wide PWM Frequency:

Adjustable 280 kHz to 700 kHz

Load Protected at Thermal Shutdown

Integrated Solution Reduces Board Area and

Total Cost

As a member of the SWIFT family of dc/dc regulators,

the SN0401093 low-input voltage high-output current

synchronous buck PWM converter integrates all

required active components. Included on the substrate

with the listed features are a true, high performance,

voltage error amplifier that enables maximum

performance under transient conditions and flexibility in

choosing the output filter L and C components; an

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

the VIN input voltage reaches 3 V; an internally and

externally set slow-start circuit to limit in-rush currents;

and a power good output useful for processor/logic

reset, fault signaling, and supply sequencing.

APPLICATIONS

The SN0401093 is available in a thermally enhanced

28-pin TSSOP (PWP) PowerPAD package, which

eliminates bulky heatsinks.
