Texas Instruments LMR24210 / LMR24220 Step-Down Voltage Regulators
Texas Instruments LMR24210 and LMR24220 SIMPLE SWITCHER® 42Vin step-down voltage regulators in micro SMD packaging feature all the required functions to implement a highly efficient and cost-effective buck regulator. These SIMPLE SWITCHER step-down voltage regulators offer output currents up to 1.0A (LMR24210) or 2.0A (LMR24220) and up to 1MHz switching frequency. LMR242xx series step-down voltage regulators provide programmable soft-start and COT architecture with ERM for reduced component count and ultra-fast transient response. The LRM24210 and LMR24220 are ideal for point-of-load conversions from 5V, 12V, and 24V rails, space-constrained applications, industrial distributed power applications, and power meters.
