DESCRIPTION

KEY FEATURES

I 5-bit Programmable Output For CPU Core

The LX1662/62A and LX1663/63A are

Monolithic Switching Regulator Con-

troller IC’s designed to provide a low cost,

high performance adjustable power supply

for advanced microprocessors and other

applications requiring a very fast transient

response and a high degree of accuracy.

Short-Circuit Current Limiting with-

out 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 sense com-

parator threshold for optimum perfor-

mance using a PCB trace. For applications

requiring a high degree of accuracy, a

conventional sense resistor can be used to

sense current.

Programmable Synchronous Recti-

fier 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 Pentium II

processors). The 5-bit code adjusts the

output voltage between 1.30 and 2.05V in

50mVincrementsandbetween2.0and3.5V

in 100mV increments, conforming to the

Intel Corporation specification. The device

candrivedualMOSFET’sresultingintypical

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 (non-syn-

chronous operation).

Smallest Package Size. The LX1662 is

available in a narrow body 14-pin surface

mount IC package for space sensitive appli-

cations. TheLX1663providestheadditional

functions of Over Voltage Protection (OVP)

and Power Good (PWRGD) output drives

for applications requiring output voltage

monitoring and protection functions.

Ultra-Fast Transient Response Re-

duces System Cost. The modulated off-

time architecture results in the fastest tran-

sient response for a given inductor, reduc-

ing output capacitor requirements, and re-

ducing 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-circuit of the main MOSFET.

The LX1663 & LX1663A also have a logic-

level Power Good Flag to signal when the

output voltage is out of specified limits.
