LM22678TJE-5.0/NOPB

Понижающий импульсный стабилизатор, фиксированный, 4.5В-42В (Vin), 5В и 5A на выходе, TO-263-7.

The LM22678TJE-5.0/NOPB is a step-down Voltage Regulator with precision enable. It 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. Fixed 5V output and adjustable output voltage options are available. A switching frequency of 500kHz allows for small external components and good transient response. A precision enable input allows simplification of regulator control and system power sequencing. In shutdown mode the regulator draws only 25µA (typical).
