GA8522

Linear Artwork GA8522 300KHz, 2A Step-Down DC-DC Converter v General Description The GA8522 is a voltage mode, step-down DC-DC converter that is designed to meet 2A output current and utilizes PWM control scheme that switches with 300KHz fixed frequency. This device includes a reference voltage source, error amplifier, oscillation circuit, P-channel MOSFET, and etc. The input voltage range of GA8522 is from 3.6V to 23V, and provides adjustable output voltage range from 0.8V to VIN for customers in application. The GA8522 provides an enable function that can be controlled by external logic signal and excellent regulation during line or load transient due to the internal compensation. Other features of thermal protection, current limit and short circuit protection are also included. Due to the low Drain-Source resistance of internal power MOSFET, the GA8522 provides a high efficiency step-down application. It can also operate with a maximum duty cycle of 100% for use in low drop-out conditions. The package is available in a standard SOP-8L. v Features Adjustable Output Voltage from 0.8V to VIN Operating Input Voltage up to 23V Great Output Capability: 2A Oscillation Frequency: 300KHz Built-in P-channel MOSFET External ON/OFF Control Function Low Shutdown Current: 1uA Current Limit and Thermal Protection Short Circuit Protection Stable With Low ESR Output Ceramic Capacitor SOP-8L Package All Products meet Rohs Standard v Applications Broadband Commun...
