Synchronous Buck FET Driver Optimized for High-Frequency Applications

Check for Samples: TPS51604

FEATURES

DESCRIPTION

•

Reduced Dead-Time Drive Circuit for

Optimized CCM

The TPS51604 drivers are optimized for high-

frequency CPU V_COREapplications. Advanced

features such as reduced dead-time drive and Auto

Zero Crossing are used to optimize efficiency over

the entire load range.

Automatic Zero Crossing Detection for

Optimized DCM Efficiency

Multiple Low-Power Modes for Optimized

Light-Load Efficiency

The SKIP pin provides immediate CCM operation to

support controlled management of the output voltage.

In addition, the TPS51604 supports two low-power

modes. With the PWM input in tri-state, quiescent

current is reduced to 130 µA, with immediate

response. When SKIP is held at tri-state, the current

is reduced to 8 µA (typically 20 µs is required to

resume switching). Paired with the appropriate TI

controller, the drivers deliver an exceptionally high

performance power supply system.

Optimized Signal Path Delays for High-

Frequency Operation

Integrated BST Switch Drive Strength

Optimized for Ultrabook FETs

•

Optimized for 5-V FET Drive

Conversion Input Voltage Range (V_IN): 4.5 V to

28 V

•

Small, 2 mm x 2 mm, 8-Pin, SON Power Pad

Package

The TPS51604 is packaged in a space saving,

thermally enhanced 8-pin, 2 mm x 2 mm SON

package and operates from –40°C to 105°C.
