LM20123 | 具有可選汽車級的 2.95V 至 5.5V、3A、電流模式同步降壓穩(wěn)壓器; ? LM20123Q is AEC-Q100 Qualified and Manufactured on an Automotive Grade Flow\n? Input Voltage Range 2.95V to 5.5V\n? Accurate Current Limit Minimizes Inductor Size\n? 96% Efficiency with 1.5 MHz Switching Frequency\n? 32 m? Integrated FET Switches\n? Starts up into Pre-Biased Loads\n? Output Voltage Tracking\n? Peak Current Mode Control\n? Adjustable Output Voltage Down to 0.8V\n? Adjustable Soft-Start with External Capacitor\n? Precision Enable Pin with Hysteresis\n? Integrated OVP, UVLO, Power Good and Thermal Shutdown\n? HTSSOP (16-Pins) Exposed Pad Package; The LM20123 is a full featured 1.5 MHz synchronous buck regulator capable of delivering up to 3A of continuous output current. The current mode control loop can be compensated to be stable with virtually any type of output capacitor. For most cases, compensating the device only requires two external components, providing maximum flexibility and ease of use. The device is optimized to work over the input voltage range of 2.95V to 5.5V making it suited for a wide variety of low voltage systems.The device features internal over voltage protection (OVP) and over current protection (OCP) circuits for increased system reliability. A precision enable pin and integrated UVLO allows the turn on of the device to be tightly controlled and sequenced. Start-up inrush currents are limited by both an internally fixed and externally adjustable Soft-Start circuit. Fault detection and supply sequencing is possible with the integrated power good circuit. The LM20123 is designed to work well in multi-rail power supply architectures. The output voltage of the device can be configured to track a higher voltage rail using the SS/TRK pin. If the output of the LM20123 is pre-biased at startup it will not sink current to pull the output low until the internal soft-start ramp exceeds the voltage at the feedback pin. The LM20123 is offered in a 16-pin HTSSOP package with an exposed pad that can be soldered to the PCB, eliminating the need for bulky heatsinks. | TITexas Instruments 德州儀器美國德州儀器公司 | TI | |
