LMR62421 Step-Up Voltage Regulators Texas Instruments LMR62421 SIMPLE SWITCHER® Step-Up Voltage Regulators are easy-to-use, space-efficient 2.1A low-side switch regulators ideal for Boost and SEPIC DC-DC regulation. LMR62421 offers all the active functions to provide local DC/DC conversion with fast- transient response and accurate regulation in the smallest PCB area. With a switching frequency that is internally set to 1.6MHz, LMR62421 enables the use of extremely small surface mount inductor and chip capacitors while providing efficiencies near 90%. Current-mode control and internal compensation provide ease-of-use, minimal component count, and high-performance regulation over a wide range of operating conditions. External shutdown features an ultra-low standby current of 80nA ideal for portable applications. Tiny 5-pin SOT-23 and 6-pin WSON packages provide space-savings. Additional features include internal soft-start, circuitry to reduce inrush current, pulse-by- pulse current limit, and thermal shutdown.
