STMicroelectronics ST755
The ST755 is an adjustable inverting switch-mode DC-DC rergulator with internal Power MOSFET that generaters an adjustable negative output from a voltage input of 2.7V to 11V, output current guaranteed at 200mA (for BLOCK DIAGRAM Vin>4.5V, Vout = -5V and 0oC ≤ Ta ≤ 70oC) and 275mA (typical value at Ta = 25 oC, Vout = -5V).| Part No. | ST755 |
