General Description
The TD1722 is a voltage mode, fixed 200kHz/300kHz/600kHz switching frequency, synchronous buck converter. The APW 8722 allows wide input voltage that is either a single 5~1 2V or two supply voltage(s) for various applications. A power-on-reset (POR) circuit monitors the VCC supply voltage to prevent wrong logic controls.
