DC-DC преобразователи интегральные LM22679TJ-ADJ/NOPB

Импульсный понижающий DC-DC стабилизатор , регулируемый, 4.5В-42В (Vin), 1.285В-37В, 5А, TO-263-7

The LM22679TJ-ADJ/NOPB is a SIMPLE SWITCHER® Step-down Voltage Regulator with adjustable soft-start and current limit. This 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 that can provide up to 5A 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. Available in an adjustable output voltage version and 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.
