RT8070ZSP 开关电源控制芯片
资料介绍
RT8070ZSP 开关电源控制芯片，4A, 2MHz, Synchronous Step-Down Converter
General Description The RT8070 is a high efficiency synchronous, step-down DC/DC converter. Its input voltage range is from 2.7V to 5.5V and provides an adjustable regulated output voltage from 0.8V to 5V while delivering up to 4A of output current. The internal synchronous low on-resistance power switches increase efficiency and eliminate the need for an external Schottky diode. The default switching frequency is set at 2MHz, if the RT pin is left open. It can also be varied from 200kHz to 2MHz by adding an external resistor. Current mode operation with external compensation allows the transient response to be optimized over a wide range of loads and output capacitors.
Features High Efficiency : Up to 95% Adjustable Frequency : 200kHz to 2MHz No Schottky Diode Required 0.8V Reference Allows Low Output Voltage Low Dropout Operation : 100% Duty Cycle Enable Function External Soft-Start Power Good Function RoHS Compliant and Halogen Free
