The ADPL21610 switching regulators combine a 42V, 1.1A switch with a soft-start function. The ADPL21610 switches at 1.3MHz, allowing the use of tiny, low-cost and low-height inductors and capacitors. High inrush current at start-up is eliminated using the programmable soft-start function. A single external capacitor sets the current ramp rate. A constant-frequency current mode pulse-width modulator (PWM) architecture results in low, predictable output noise that is easy to filter.
The high-voltage switch on the ADPL21610 is rated at 42V, making the devices ideal for boost converters up to 40V, as well as SEPIC and flyback designs. The ADPL21610 is available in a low-profile (1mm) 6-lead Small outline transistor (SOT)‑23 package and tiny 3mm × 2mm DFN package.
