TD1722
General Description
Features
The TD1722 is a voltage mode, fixed 200kHz/300kHz/600kHz Wide 5V to 12V Supply Voltage
switching frequency, synchronous buck converter. The APW Power-On-Reset Monitoring on VCC
8722 allows wide input voltage that is either a single 5~1 Excellent Output Voltage Regulations
2V or two supply voltage(s) for various applications. A 0.6V Internal Reference for TD1722/A/D
power-on-reset (POR) circuit monitors the VCC supply voltage 0.8V Internal Reference for TD1722B/C
to prevent wrong logic controls.
±0.6% Over-Temperature Range
A built- in soft-start circuit prevents the output voltages from Integrated Soft-Start
over- shoot as well as limits the input current.
