1.产品概述(DESCRIPTION)
      The JTM1482 is a current mode monolithic buck switching regulator. Operating with an input range of 4.6-20V, the JTM1482 delivers 2A of continuous output current with two integrated  N-Channel MOSFETs.   
       The JTM1482 internal synchronous  power switches provide high efficiency without the JTM1482 use of an external Schottky diode. At light  loads, regulators operate in low frequency to  maintain high efficiency and low output ripple.  Current mode control provides tight load transient  response and cycle-by-cycle current limit.
      The guarantees robustness with   short-circuit protection, thermal protection,  start-up current run-away protection, and input  under voltage lockout. The JTM1482 is available in an 8-pin SOP  package, which provides a compact solution with  minimal external components.
