Design

MOSFET’s resulting in typical efficiencies of 85

- 90% even with loads in excess of 10 amperes.

For cost sensitive applications, the bottom

MOSFET can be replaced with a Schottky diode

requiring a very fast transient response and a high (non-synchronous operation).

Smallest Package Size. The LX1662 is available

in a narrow body 14-pin surface mount IC

package for space sensitive applications. The

LX1663 provides the additional functions of

Over Voltage Protection (OVP) and Power Good

Short-Circuit Current Limiting without

Expensive Current Sense Resistors. Current-

sensing mechanism can use PCB trace resistance

or the parasitic resistance of the main inductor.

The LX1662A and LX1663A have reduced current (PWRGD) output drives for applications

sense comparator threshold for optimum

performance using a PCB trace. For applications

requiring a high degree of accuracy, a

conventional sense resistor can be used to sense

current.

Programmable Synchronous Rectifier Driver

for CPU Core. The main output is adjustable

from 1.3V to 3.5V using a 5-bit code. The IC can

read a VID signal set by a DIP switch on the

motherboard, or hardwired into the processor’s

package (as in the case of Pentium® Pro and

requiring output voltage monitoring and

protection functions.

Available Over-Voltage

Ultra-Fast Transient Response Reduces

System Cost. The modulated offtime architecture

results in the fastest transient response for a given

inductor, reducing output capacitor requirements,

and reducing the total regulator system cost.

Over-Voltage Protection and Power Good

Flag. The OVP output in the LX1663 &

LX1663A can be used to drive an SCR crowbar

circuit to protect the load in the event of a short-
