L7980规格书详情
描述 Description
The L7980 device is a step-down switching regulator with a 2.5 A (minimum) current limited embedded Power MOSFET, so it is able to deliver up to 2 A current to the load depending on the application conditions.
The input voltage can range from 4.5 V to 28 V, while the output voltage can be set starting from 0.6 V to VIN.
Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz.
The QFN and the HSOP packages with exposed pad allow reducing the RthJAdown to 60 °C/W and 40 °C/W respectively.
特性 Features
• 2 A DC output current
• 4.5 V to 28 V input voltage
• Output voltage adjustable from 0.6 V
• 250 kHz switching frequency, programmable up to 1 MHz
• Internal soft-start and enable
• Low dropout operation: 100% duty cycle
• Voltage feed-forward
• Zero load current operation
• Overcurrent and thermal protection
• VFQFPN 3 x 3 - 8L and HSOP8 package
简介
L7980属于集成电路(IC)的稳压器-DC-DC开关稳压器。由制造生产的L7980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。
