DESCRIPTION

•

High Initial Reference Accuracy

Low Output Ripple

The TPS53114 is

single, adaptive on-time

D-CAP2™ mode synchronous buck controller. The

part enables system designers to cost effectively

complete the suite of various end equipment's power

bus regulators with a low external component count

and low standby consumption. The main control loop

for the TPS53114 uses the D-CAP2™ mode topology

which provides a very fast transient response with no

external components. The TPS53114 also has a

PROPRIETARY circuit that enables the device to

adapt to not only low equivalent series resistance

(ESR) output capacitors such as POSCAP/SP-CAP,

but also ceramic using the CER pin. The part

provides convenient and efficient operation with

conversion voltages from 4.5V to 24V and output

voltage from 0.76V to 5.5V.

Wide Input Voltage Range: 4.5V to 24V

Output Voltage Range: 0.76V to 5.5V

Low-Side R_DS(on)Loss-less Current Sensing

Adaptive Gate Drivers with Integrated Boost

Diode

•

Adjustable Soft Start

Pre-Biased Soft Start

Selectable Switching frequency

350kHz/700kHz

•

Built-In 5V Linear Regulator

The TPS53114 is available in the 16 pin TSSOP

package, and is specified from –40°C to 85°C

temperature range.
