illustrate

LM20133 - это полнофункциональный синхронный понижающий стабилизатор, способный обеспечивать непрерывный выходной ток до 3 А. The current-mode control loop can be compensated and stabilized with almost any type of output capacitor. In most cases, compensation devices, which require only two external components, provide maximum flexibility and ease of use. Optimized operation from 2.95V to 5.5V input voltage range, making it suitable for a wide range of devices in low voltage systems.

The device features internal overvoltage protection (OVP) and overcurrent protection (OCP) circuitry to improve system reliability. A high-precision enable pin and integrated undervoltage lockout allow for tight control and sequencing of the device. Both a fixed internally and externally adjustable soft-start circuit start-up inrush current is limited. Possible with integrated power good circuit fault detection and power sequencing.

Частота переключения LM20133 может быть синхронизирована с внешними часами с помощью контакта SYNC. Вывод SYNC синхронизирует диапазон входного сигнала от 500 кГц до 1,5 МГц.

LM20133 работает над архитектурой питания с несколькими шинами. The output voltage of the device can be configured to track a higher voltage rail, using SS/TRK pins. Если входящее предварительное смещение выходного сигнала LM20133 включено, оно не потребляет ток и не снижает выходной сигнал до тех пор, пока внутренняя рампа плавного пуска не превысит контакт обратной связи по напряжению.

LM20133 доступен в 16-контактном корпусе eTSSOP с открытыми контактными площадками, которые можно припаять к печатной плате, устраняя необходимость в громоздких радиаторах.
