The LP3773B is a Power Management Integrated Circuit (PMIC) specifically designed to meet the power supply and management needs of small and ultra-small form factor systems. It is an integrated single-chip SoC with up to seven voltage regulators, two buck controllers, and two low-power linear regulators. The controller has built-in EMI filters and can support up to seven output voltages including main 5V and 3.3V. Its buck controllers provide a high system efficiency of up to 300% and 12V economy mode with low standby current of 5µA. The ultra-low power linear regulators enable the gate bias of I/O and featured with resistor ladder programming and non-adjustable low current mode. The LP3773B is available in a space-saving, board-friendly SOP-7 RoHS package, with built-in protection features like overvoltage, undervoltage, over temperature, and over current protection, making it suitable for modern mobile computing, consumer and embedded applications.
