The ADPL31613 dual switching regulator combines two 38V, 1.3A switches with error amplifiers that can sense to ground, providing boost and inverting capability. The low-VCESAT bipolar switches enable the device to deliver high-current outputs in a small footprint. The ADPL31613 switches at 1.2MHz, enabling the use of tiny, low-cost, low-profile inductors and capacitors. High inrush current at start-up is eliminated by the programmable soft-start function, in which an external resistor-capacitor (RC) sets the current ramp rate. A constant-frequency current-mode pulse width modulation (PWM) architecture results in low, predictable output noise that is easy to filter.
The ADPL31613 switches are rated at 40V, making the device ideal for boost converters up to ±38V, and for SEPIC and flyback designs. Each channel can generate 5V at up to 630mA from a 3.3V supply, or 5V at 510mA from four alkaline cells in a single-ended primary inductor converter (SEPIC) design. The device can be configured as two boosts, a boost and inverter, or two inverters.
The ADPL31613 is available in a low-profile (0.75mm) 10-lead 3mm × 3mm DFN package.
