LM22676MRX-ADJ/NOPB TI Voltage Regulators - DC DC Switching Regulators
The LM22676 is a SIMPLE SWITCHER® voltage-mode step-down regulator delivering up to 3 A from a 4.5 V to 42 V input, with an adjustable output from 1.285 V to 37 V . It features a fixed 500 kHz switching frequency, an integrated high-side N-channel MOSFET, and requires minimal external components . The device includes a precision enable for programmable UVLO, cycle-by-cycle current limiting, and thermal shutdown . Quiescent current is 3.4 mA typical, with efficiency up to 90% and a maximum duty cycle of 90% . Selection is ideal for industrial and automotive power supplies requiring a wide input range and 3 A output capability. Applications include 12 V to 5 V conversion for factory automation, automotive infotainment systems, telecom equipment, and battery-powered industrial devices.
