LMR62421 Datasheet PDF

●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

● Fully enabled for WEBENCH® power designer

● Green product and no Sb/Br

●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
