NCP1594B

Buck Converter High-Efficiency, Synchronous 4 A, 6 A, 2 MHz NCP1594A, NCP1594B The NCP1594 is a high−output−current synchronous PWM converter that integrates two N−channel Power MOSFETs. The NCP1594 utilizes externally compensated voltage mode control to provide good transient response, ease of implementation, and excellent loop stability. It regulates input voltages from 2.9 V to 6.0 V down to an output voltage as low as 0.6 V and is able to supply up to 4.0 A of load current (NCP1594A). Please contact factory for NCP1594B which supports 6.0 A load current. The NCP1594 includes an internal soft−start to limit inrush current. Other features include cycle−by−cycle current limit, 92% max duty cycle, short−circuit protection, and thermal shutdown. Features Wide Input Voltage Range from 2.9 V to 6.0 V Nine Preset Output Voltages (0.6 V, 0.7 V, 0.8 V, 1.0 V, 1.2 V, 1.5 V, 1.8 V, 2.0 V, and 2.5 V) Adjustable Output Voltage Down to 0.6 V Adjustable 500 kHz to 2 MHz Switching Frequency Externally Adjustable Soft−Start and Able to Start Up with Pre−Biased Output Load Selectable Forced PWM with and without Pre−biased Startup Compatible with Ceramic, Polymer, and Electrolytic Output Capacitors Cycle−by−Cycle Current Limiting Hiccup Mode Short−Circuit Protection Over Temperature Protection This is a 24 Pin 4 x 4 mm 0.5P WQFN Pb−Free Device These are Pb−Free Devices Typical Applications Telecom and Networking Power Management Computing Power Management Datac...
