YB1161 is a high efficiency synchronous boost converter with ultra-low quiescent current as low as 1pA (Yucan) [Copy link]

Introduction:

The YB1161 is a high efficiency synchronous boost converter with ultra low quiescent current as low as 1pA. It is capable of delivering at least 2W of power from a low voltage source, i.e. 0.4A at 5V output. It also features a true shutdown function that disconnects the input and output during shutdown and short circuit conditions. This eliminates the need for external MOSFETs and their control circuitry to disconnect the input from the output and provides robust output overload protection. The 1.4MHz switching frequency allows the use of miniature and thin inductors and ceramic capacitors. With its ultra low LQ characteristics, the YB1161 is an ideal choice for solving problems that require low standby power and compact board size, such as IoT applications. The YB1161s are packaged in SOT23-6 and DFN2x2-6 packages
