TPS54320

illustrate

El TPS54320 es un convertidor reductor de 17V y 3A con todas las funciones optimizado para una alta eficiencia y un diseño pequeño que integra MOSFET de lado alto y lado bajo para un reductor sincrónico. Further space savings are achieved through current mode control, which reduces and selects a high switching frequency, reducing the inductor's footprint component count.

The output voltage starts the SS/sail pin for ramp control, allowing operation either as a standalone power supply or in a tracking case. Power sequencing can also be done by properly configuring the start-up and open-drain power good pins.

The protection device under overload conditions by periodic current to the high-side FET cycle limit is increased by the purchaser of low current limit to prevent current runaway.
