DESCRIPTION ?
The ? IR3553 ? integrated ? PowIRstage? ? is ? a ? synchronous ? buck ?
gate ? driver ? co ‐ packed ? with ? a ? control ? MOSFET ? and ? a ?
synchronous ? MOSFET ? with ? integrated ? Schottky ? diode. ? It ? is ?
optimized ? internally ? for ? PCB ? layout, ? heat ? transfer ? and ?
driver/MOSFET ? timing. ? Custom ? designed ? gate ? driver ? and ?
MOSFET ? combination ? enables ? higher ? efficiency ? at ? lower ?
output ? voltages ? required ? by ? cutting ? edge ? CPU, ? GPU ? and ?
DDR ? memory ? designs. ??
Up ? to ? 1.0MHz ? switching ? frequency ? enables ? high ?
performance ? transient ? response, ? allowing ? miniaturization ?
of ? output ? inductors, ? as ? well ? as ? input ? and ? output ? capacitors ?
while ? maintaining ? industry ? leading ? efficiency. ? The ? IR3553’s ?
superior ? efficiency ? enables ? smallest ? size ? and ? lower ? solution ?
cost. ? The ? IR3553 ? PCB ? footprint ? is ? compatible ? with ? the ?
IR3550 ? (60A) ? and ? the ? IR3551 ? (50A). ?
Integrated ? current ? sense ? amplifier ? achieves ? superior ?
current ? sense ? accuracy ? and ? signal ? to ? noise ? ratio ? vs. ? best ‐ in ‐
class ? controller ? based ? Inductor ? DCR ? sense ? methods. ?
The ? IR3553 ? incorporates ? the ? Body ‐? Braking? ? feature ? which ?
enables ? reduction ? of ? output ? capacitors. ? Synchronous ? diode ?
emulation ? mode ? in ? the ? IR3553 ? removes ? the ? zero ‐ current ?
detection ? burden ? from ? the ? PWM ? controller ? and ? increases ?
system ? light ‐ load ? efficiency. ?
The ? IR3553 ? is ? optimized ? specifically ? for ? CPU ? core ? power ?
delivery ? in ? server ? applications. ? The ? ability ? to ? meet ? the ?
stringent ? requirements ? of ? the ? server ? market ? also ? makes ?
the ? IR3553 ? ideally ? suited ? to ? powering ? GPU ? and ? DDR ?
memory ? designs ? and ? other ? high ? current ? applications. ?
