LMR62421XMFE/NOPB TI Voltage Regulators - DC DC Switching Regulators
The LMR62421 is a boost and SEPIC converter with a 2.1 A integrated switch, operating from 2.7 V to 5.5 V input and providing an adjustable output up to 24 V . It features a fixed 1.6 MHz switching frequency, allowing for small external components and low output ripple. Current-mode control provides excellent line and load regulation. The device includes cycle-by-cycle current limiting and thermal shutdown for robust protection. Packaged in a 5-pin SOT-23, it is ideal for battery-powered portable applications requiring high-voltage generation from a low-voltage source. Applications include LCD bias supplies, white LED backlight drivers for portable displays, portable medical instruments, and SEPIC converters requiring an output voltage above or below the input voltage .
