Texas Instruments LMR62421XMF/NOPB DC-DC Switching Boost Sepic Regulator Adjustable 2.7V-5.5Vin 3V-24Vout 2.1Aout SOT-23-5

The LMR62421XMF/NOPB is a SIMPLE SWITCHER« 24Vout 2.1A Step-up Voltage Regulator ideal for Boost and SEPIC DC-DC regulation. It provides all the active functions to provide local DC/DC conversion with fast-transient response and accurate regulation in the smallest PCB area. Switching frequency is internally set to 1.6MHz, allowing 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. Additional features include internal soft-start, circuitry to reduce inrush current, pulse-by-pulse current limit and thermal shutdown.

• 1.6MHz Switching frequency
• 80nA Low shutdown
• Cycle-by-cycle current limiting
• Internally compensated
• Green product and no Sb/Br
