DC-DC开关降压稳压器, 可调, 260 kHz, 8V-40V输入, 1.2V-37V/5A输出, TO-263-7
The LM2679 series of regulators are monolithic integrated circuits which provide all of the active functions for a step-down buck switching regulator capable of driving up to 5-A loads with excellent line and load regulation characteristics. High efficiency >90% is obtained through the use of a low ON-resistance DMOS power switch. The series consists of fixed output voltages of 3.3 V, 5 V, and 12 V and an adjustable output version.
The SIMPLE SWITCHER® concept provides for a complete design using a minimum number of external components. A high fixed frequency oscillator 260 kHz allows the use of physically smaller sized components. A family of standard inductors for use with the LM2679 are available from several manufacturers to greatly simplify the design process.
Other features include the ability to reduce the input surge current at power on by adding a soft-start timing capacitor to gradually turn on the regulator. The LM2679 series also has built-in thermal shutdown and resistor programmable current limit of the power MOSFET switch to protect the device and load circuitry under fault conditions. The output voltage is specified to a ±2% tolerance. The clock frequency is controlled to within a ±11% tolerance.
