TEXAS INSTRUMENTS TPS560200DBVR 直流-直流开关降压, 逐步递降稳压器, 可调, 4.5V-17V输入, 800mV-6.5V/500mA输出, SOT-23-5 新
Description
The TPS560200 is an 17-V, 500-mA, low-Iq, adaptive on-time D-CAP2 mode synchronous monolithic buck converter with integrated MOSFETs in easy-to-use 5-pin SOT-23 package.
The TPS560200 lets system designers complete the suite of various end-equipment power bus regulators with a cost-effective, low component count and low standby current solution. The main control loop for the device uses the D-CAP2 mode control that provides a fast transient response with no external compensation components. The adaptive on-time control supports seamless transition between PWM mode at higher load conditions and advanced Eco Mode operation at light loads.
