YB1696 is a switch power supply chip produced by Yobon. It supports 5V and adjustable output versions. The adjustable version output voltage range is 1.23V to 28V, with a maximum deviation of +4%. The operating frequency is 150KHz. This chip has over-temperature protection and over-current protection functions.
The YB1696 series provides a monolithic step‑down DC/DC solution with a fixed 150 kHz switching frequency. It can deliver up to 3 A load current while maintaining good line and load regulation, and includes built‑in thermal‑shutdown and current‑limit protection. The device is offered in both fixed‑output (5 V) and adjustable versions, with the latter allowing output voltages from 1.23 V to 28 V.
Typical applications include battery chargers and other low‑power systems where a compact, efficient regulator is required. The regulator operates from an input voltage range of 4.5 V to 32 V, and its efficiency reaches up to 80 % at 12 V input and 3 A load. The TO‑263‑5L package provides good thermal performance when mounted on a PCB with adequate copper area and heat‑dissipating layout.
