PRELIMINARY TECHNICAL DATA

High-Efficiency Notebook Computer

Power Supply Controller

ADP3026

Preliminary Technical Data

GENERAL DESCRIPTION

FEATURES

The ADP3026 is a highly efficient dual synchronous buck

switching regulator controller optimized for converting the

battery or adapter input into the system supply voltages re-

quired in notebook computers. The ADP3026 uses a

dual-mode PWM/Power Saving Mode architecture to maintain

efficiency over a wide load range.

Wide Input Voltage Range: 6.5 V to 25 V

High Conversion Efficiency > 96%

Integrated Current Sense—No External Resistor Re-

quired

Low Shutdown Current: 14 ␮A (Typical)

Voltage Mode PWM with Input Feed Forward for Fast

Line Transient Response

Dual Synchronous Buck Controllers with PWM/

Power-Saving Mode Operation

Built-In Gate Drive Boost Circuit for Driving Exter-

nal

The ADP3026 provides accurate and reliable short circuit

protection using an internal current sense circuit, which re-

duces cost and increases overall efficiency. Other protection

features include programmable soft-start, UVLO, and inte-

grated output undervoltage/overvoltage protection.

N-Channel MOSFETs

Two Fixed Output Voltages: 3.3 V, 5 V

PWM Frequency: 300 kHz

Extensive Circuit Protection Functions

28-Lead TSSOP Package

APPLICATIONS

Notebook Computers and PDAs

Portable Instruments

General Purpose DC-DC Converters
