PAM2321中文资料3MHz, FAST TRANSIENT 2A STEP-DOWN CONVERTER数据手册Diodes规格书

描述 Description

The PAM2321 is a 2A step-down converter with a typical input
voltage of 3.3V and a fixed output voltage of 1.2V or an adjustable
output. The 3MHz switching frequency enables the use of small
external components. The ultra-small 3mmx3mm footprint and high
efficiency make the PAM2321 an ideal choice for portable
applications.

The PAM2321 delivers 2A maximum output current while consuming
only 55μA no-load quiescent current. Low RDS(ON) integrated
MOSFETs and 100% duty cycle operation make the PAM2321 the
ideal choice for high output voltage, high current applications which
require a low dropout threshold.

The PAM2321 provides excellent transient response and output
accuracy across the operating range.

The PAM2321 maintains high efficiency throughout the load range.
The PAM2321 automatically optimizes efficiency during light load
mode (PSM) and maintains constant frequency and low output ripple
during PWM mode.

Over-temperature and short circuit protection safeguard the PAM2321
and system components from damage.

The PAM2321 are available in Pb-free, ultrasmall, low profile,
TDFN3X3-10 packages. The product is rated over a
temperature range of -40°C to +85°C.

简介

PAM2321属于集成电路（IC）的稳压器-DC-DC开关稳压器。由Diodes制造生产的PAM2321稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。
