The IW1602-00B with switching controllers SOT-23 RoHS is a 6-pin integrated circuit (IC) that is manufactured by Dialog Semiconductor. It is a highly integrated single-chip, Buck-Mode, Synchronous, Step-Down switching controller designed to deliver up to 1.5A of output current. It features a proprietary architecture that includes enhanced Pulse Frequency Modulation (PFM) and pulse-skipping techniques, operating at a 2.5MHz constant frequency which allows the use of tiny external components. Additionally, the controller supports a wide range of input voltages from 0.8V to 10V and output voltages from 0.3V to 5V. It is optimized for low EMI and high efficiency over a wide range of loads. The IC also provides protection functions such as Over Voltage Protection, Under Voltage Protection, Thermal Shutdown, and Overcurrent Protection. The IW1602-00B is offered in a Lead-Free RoHS-compliant SOT-23 package, making it an ideal solution for portable and/or battery operated applications.
