3 Description
The TPS62993-Q1 is a highly efficient, small, and
flexible synchronous step-down DC-DC converter that
is easy to use. A selectable switching frequency of 2.5
MHz or 1.0 MHz allows the use of small inductors and
provides fast transient response. The device supports
high VOUT accuracy of ± 1.5 across the entire
operasting temperature range and enhanced load
transient performance with the DCS-Control topology.
The wide 3-V to 10-V input voltage range supports a
variety of nominal inputs, like 9-V supply rails, singlecell
or multi-cell Li-Ion, and 5-V or 3.3-V rails.
The TPS62993-Q1 can automatically enter power
save mode (if auto PFM or PWM is selected) at
light loads to maintain high efficiency. Additionally,
to provide high efficiency at very small loads, the
device has a low typical quiescent current of 4 μA.
AEE, if enabled, provides high efficiency across VIN,
VOUT, and load current. The device includes a MODE/
Smart-CONF input to set the internal and external
divider, switching frequency, output voltage discharge,
and automatic power save mode or forced PWM
operation.
TPS62903属于集成电路(IC) > 稳压器 - DC-DC 开关稳压器。美国德州仪器公司制造生产的TPS62903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。
