N1153 General Description
The N1153 is a low-cost, 5 bit TTL-compatible input, digital-to-analog (DAC) programmable, synchronous buck converter controller design-ed specifically to power the Pentium ® II as well as the next generation of P6 family or other high performance core logic in desktop person-al computer CPU applications.
Additional features also include temperature compensated voltage reference, triangle wave oscillator, current limits comparator, frequency shift over-current protection, and an access-ible, internally compensated error amplifier, power good signal, logic compatible shutdown, and over voltage protection are also provide.
The N1153 operates at a fixed 200KHz, provid-ing an optimum compromise between efficien-cy, external component size, and cost.
