LM22671MR-5.0/NOPB

Понижающий импульсный стабилизатор, фиксированный, 4.5В-42В (Vin), 5В и 0.5A на выходе, HSOP-8.

The LM22671MR-5.0/NOPB is a SIMPLE SWITCHER fixed output step down switching regulator with adjustable frequency in 8 pin HSOP (SO PowerPAD) package. This switching regulator provides all of the functions necessary to implement an efficient high voltage step down (buck) regulator using a minimum of external components. It provides excellent line and load regulation along with high efficiency (> 90%). Voltage mode control offers short minimum on-time allowing the widest ratio between input and output voltages. In addition, the frequency can be adjusted over a range of 200KHz to 1MHz with a single external resistor. The internal oscillator can be synchronized to a system clock or to the oscillator of another regulator. During shutdown mode, the regulator draws only 25µA typically.
