PS8A0101AWEX is a single-package two-phase integrated switching regulator with power system (PMIC) designed to meet special application needs in the field of power management. Such applications include battery powered automotive functions, wireless charging, high voltage motors, or a variety of other powersystem applications that require high efficiency, ultra-low power and low component count.

The PS8A0101AWEX is a sophisticated power module that integrates a wide range of power component and circuit function elements. PMIC enables complex power supply and power system management solutions, including starting, standby and off-mode functions, ultra-low leakage and standby current, and power-rail stabilization, thermal overload protection and automatic overload protection.

The PS8A0101AWEX is a high performance two-phase DC to DC converter, offering high system efficiency and power component performance. The two-phase switcher comprises two independent voltage regulators, which can be used to power multiple output rails operating at different voltage levels. This can be achieved through a combination of switching and linear regulation with high transient load conditions providing safe and reliable operation.

The PS8A0101AWEX features a wide input voltage range of 900V to 75V, up to 10V output voltage and up to 2A current. It also features excellent power conversion efficiency of up to 85%: high enough that the device can operated without a heatsink. The modular platform of PS8A0101AWEX also includes integrated protection functions such as over-voltage protection, over-current protection, reverse polarity protection, ESD protection and surge protection.

The PS8A0101AWEX also supports a wide range of thresholds and control functions, including automatic voltage control, output voltage selection, and adjustable output condition mode switching. The intelligent design of the PS8A0101AWEX makes it ideal for applications that require a high degree of control and flexibility.

The PS8A0101AWEX operates on a simple but efficient working principle. Firstly, an isolated switching regulator converts an input DC voltage to a preset output voltage. This is followed by a voltage dependent, high efficiency two-phase linear regulator, which controls the output voltage. The output voltage is monitored by two feedback loops and two error amplifiers, respectively. The output voltage is then adjusted via the adjustable threshold level of the above mentioned two error amplifiers.

The PS8A0101AWEX was designed primarily to meet the needs of specialized power management applications, such as those in automotive, wireless charging, high voltage motors, and other power system related applications. The versatility and functionality of the PS8A0101AWEX make it an ideal choice for these applications.
