1 / 5 page TS2580 2A / 52KHz Buck Switching Regulator 1/5 Version: B11 SOP-8 General Description TS2580 Series are step-down switching regulators with all required active functions. It is capable of driving 2A load with excellent line and load regulations. These devices are available for adjustable output version. TS2580 series operates at a switching frequency of 52kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. It substantially not only reduces the area of board size but also the size of heat sink, and in some cases no heat sink is required. The ±4% tolerance on output voltage within specified input voltages and output load conditions is guaranteed. Also, the oscillator frequency accuracy is within ±10%. External shutdown is included. Featuring 100µA (typical) standby current. The output switch includes cycle- by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions. Features ● Adjustable Output Voltage Range 1.23V~38.5V ● 52kHz fixed switching frequency ● Voltage Mode Non-synchronous PWM control ● Thermal Shutdown and Current Limit Protection ● ON/OFF Shutdown Control Input ● Short Circuit Protect (SCP) ● Operating Voltage Can be up to 40V ● Output Load Current 2A ● Low Power Standby Mode Ordering Information Part No. Package Packing TS2580CS RL SOP-8 2.5kpcs / 13” Reel TS2580CS RLG SOP-8 2.5kpcs / 13” Reel Note: “G” denotes Halogen Free Product.
