LM22676TJ-ADJ
TEXAS INSTRUMENTS LM22676TJ-ADJ 直流-直流开关降压逐步递减稳压器, 可调, 4.5V-42V输入, 1.285V-37V输出, 3A输出, TO-263-7
The 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. A precision enable input allows simplification of regulator control and system power sequencing. In shutdown mode the regulator draws only 25µA typical. Built-in soft-start 500µs, typical saves external components.
