TS2596 is a switching power supply chip launched by Sanan Optoelectronics. It has a maximum output current of 3A and supports 3.3V and 5V fixed output voltages and adjustable output voltage. The working frequency is 150kHz, with high reliability and good heat dissipation performance.
The TS2596 series are step‑down switching regulators that provide up to 3 A load current with excellent line and load regulation. They are offered in fixed 3.3 V and 5 V versions as well as an adjustable output version, and operate at a switching frequency of 150 kHz, allowing the use of small filter components.
Key features include a wide input voltage range up to 40 V, low standby current, cycle‑by‑cycle current limiting, thermal shutdown protection, and optional external shutdown. The datasheet provides electrical characteristics, typical application circuits, component selection tables, and mechanical drawings for both TO‑220‑5L and TO‑263‑5L packages.
