LM22676MRX-5.0/NOPB SMD/SMT Texas Instruments SO-PowerPad-8                                              1 The LM22676 switching regulator provides all of the • Wide Input Voltage Range: 4.5 V to 42 V functions necessary to implement an efficient high • Internally Compensated Voltage Mode Control voltage step-down (buck) regulator using a minimum • Stable with Low ESR Ceramic Capacitors of external components. This easy to use regulator • 120 mΩ N-Channel MOSFET PFM Package incorporates a 42 V N-channel MOSFET switch capable of providing up to 3 A of load current. • 100 mΩ N-Channel MOSFET PSOP-8 Package Excellent line and load regulation along with high • Output Voltage Options: efficiency (> 90%) are featured. Voltage mode control -ADJ (Outputs as Low as 1.285 V) offers short minimum on-time, allowing the widest -5.0 (Output Fixed to 5 V) ratio between input and output voltages. Internal loop • ±1.5% Feedback Reference Accuracy compensation means that the user is free from the tedious task of calculating the loop compensation • Switching Frequency of 500 kHz components. Fixed 5 V output and adjustable output • –40°C to 125°C Operating Junction voltage options are available. A switching frequency Temperature Range of 500 kHz allows for small external components and good transient response. A precision enable input • Precision Enable Pin allows simplification of regulator control and system • Integrated Boot-Strap Diode power sequencing. In shutdown mode the regulator • Integrated Soft-Start draws only 25 µA (typ). Built in soft-start (500 µs, typ) • Fully WEBENCH saves external components. The LM22676 also has ® Enabled built in thermal shutdown, and current limiting to • LM22676Q is an Automotive Grade Product protect against accidental overloads.
