LT1375/LT1376 1.5A, 500kHz Step-Down Switching Regulators FEATURES s s s s s s s s Constant 500kHz Switching Frequency Easily Synchronizable Uses All Surface Mount Components Inductor Size Reduced to 5µH Saturating Switch Design: 0.4Ω Effective Supply Current: 2.5mA Shutdown Current: 20µA Cycle-by-Cycle Current Limiting is current mode for fast transient response and good loop stability. Both fixed output voltage and adjustable parts are available. A special high speed bipolar process and new design techniques achieve high efficiency at high switching frequency. Efficiency is maintained over a wide output current range by using the output to bias the circuitry and by utilizing a supply boost capacitor to saturate the power switch.
