ADPL21210 1.1A Step-Up DC/DC Converters

Analog Devices Inc. ADPL21210 1.1A Step-Up DC/DC Converters are switching regulators that combine a 26V, 1.1A switch with an integrated soft-start function. These converters feature a 330mV at 1.1A low V_CESAT switch, up to 24V high output voltage, and a 2.7V to 12V wide input voltage range. The ADPL21210 step-up DC/DC converters include a 26V high-voltage switch that helps boost converters up to 24V, as well as SEPIC and flyback designs. These converters switch at 2.1MHz, which allows the use of even smaller components. The ADPL21210 step-up DC/DC converters are available in a low-profile (1mm) 6-lead Small Outline Transistor (SOT-23) package and a tiny 3mm x 2mm DFN package. Typical applications include digital cameras, white LED power supplies, cellular phones, medical diagnostic equipment, local 5V or 12V supplies, and xDigital Subscriber Line (xDSL) power supplies.
