The BD9870 single-channel, step-down switching regulator provides 900 kHz operation that permits use of a smaller coil and ceramic output capacitor, which results in a 60% board-space savings compared with current solutions on the market. It is well suited for TVs, DVD players, PCs, car audio, and industrial equipment.
The device integrates a switching voltage regulator, 1.5 A-rated p-channel power MOSFET, and compensation circuitry into a TO-252S-5 package. It eliminates external feedback compensation components and makes designs possible using an external coil, diode, and output capacitor. The regulator offers a ±1.0% output accuracy, a bias current of 3 mA, and zero standby current. The input voltage ranges from 8 V to 35 V, with output voltage adjustable down to 1 V.
