LT1959 4.5A, 500kHz Step-Down Switching Regulator FEATURES s s s s s s s s s s s DESCRIPTIO Operates with Input as Low as 4V Output Range Down to 1.21V Constant 500kHz Switching Frequency Uses All Surface Mount Components Inductor Size Reduced to 1.8µH Saturating Switch Design: 0.07Ω Shutdown Current: 20µA Easily Synchronizable Cycle-by-Cycle Current Limiting 4.5A Switch Current Mode Control The LT ®1959 is a 500kHz monolithic buck mode switching regulator functionally identical to the LT1506 but optimized for lower output voltage applications. It will operate down to 1.21V output compared to 2.42V for the LT1506. A 4.5A switch is included on the die along with all the necessary oscillator, control and logic circuitry.
