General Description
The RT6217A/B is a simple, easy-to-use, 3A synchronous
step-down DC-DC converter with an input supply voltage
range of 4.5V to 24V. The device build-in an accurate
0.791V reference voltage and integrates low RDS(ON) power
MOSFETs to achieve high efficiency in a TSOT-23-8 (FC)
package.
The RT6217A/B adopts Advanced Constant On-Time
ACOTTM) control architecture to provide an ultrafast
transient response with few external components and to
operate in nearly constant switching frequency over the
line, load, and output voltage range. The RT6217A operates
in automatic PSM that maintains high efficiency during
light load operation. The RT6217B operates in Forced
PWM that helps meet tight voltage regulation accuracy
requirements.
The RT6217A/B senses both FETs current for a robust
over-current protection. It features cycle-by-cycle current
limit protection and prevent the device from the catastrophic
damage in output short circuit, over current or inductor
saturation. An externally adjustable soft-start function
prevents inrush current during start-up. The device also
includes input under-voltage lockout, output under-voltage
protection, and over-temperature protection (thermal
shutdown) to provide safe and smooth operation in all
operating conditions. The RT6217A/B is offered in a TSOT-
23-8(FC) package.
RT6217AHGJ8F属于集成电路(IC) > 稳压器 - DC-DC 开关稳压器。立绮科技制造生产的RT6217AHGJ8F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。
