DC-DC преобразователи интегральные LM22673MR-ADJ/NOPB

Импульсный понижающий DC-DC стабилизатор , регулируемый, 4.5В-42В (Vin), 1.285В-37В, 3А, SOP-8

The LM22673MR-ADJ/NOPB is a SIMPLE SWITCHER® step-down Voltage Regulator provides all of the functions necessary to implement an efficient high voltage step-down (buck) regulator using a minimum of external components. This easy to use regulator incorporates a 42V N-channel MOSFET switch capable of providing up to 3A of load current. Excellent line and load regulation along with high efficiency (>90%) are featured. Voltage mode control offers short minimum on-time, allowing the widest ratio between input and output voltages. Internal loop compensation means that the user is free from the tedious task of calculating the loop compensation components. A switching frequency of 500kHz allows for small external components and good transient response. An adjustable soft-start feature is provided through the selection of a single external capacitor. In addition, the switch current limit can be programmed with a single external resistor, allowing solution optimization.
