G5318
G5318 is High-Speed Step-Down Controller manufactured by Global Mixed-mode Technology.
Features - Ultra-High Efficiency - 4700ppm/°C RDS(ON) Current Sensing ( without Current-Sense Resistor ) - Quasi-PWM with 100ns Load-Step Response - Built-in 0.5% 0.7V Reference - 0.7V to 2.6V Adjustable Output Range - 4.5V to 28V Battery Input Range - 4 Selectable Frequency Setting - Integrated Boost Switch - OVP & UVP - 1.5ms Voltage Servo Soft-Start - Drives Large Synchronous-Rectifier FETs - Power-Good Indicator - Thermal Shutdown (Non-latch) General Description G5318 is a small-sized step-down controller uses constant on-time control scheme to handle wide input/output voltage ratios with ease and provides 100ns “instant-on” response to load transients while maintaining a relatively constant switching frequency. The G5318 achieves high efficiency at a reduced cost by eliminating the current-sense resistor found in traditional current-mode PWMs. Efficiency is further enhanced by an ability to...
