G5207

Global Mixed-mode Technology Inc. G5207 24V Input Voltage-Mode Buck PWM Controller Features Drives Two N-Channel MOSFETs Operates at 5V Supply Voltage Voltage-Mode PWM Control Fast Transient Response 0.8V, 2% Accuracy Reference Voltage Internal Soft Start Constant 300kHz Switching Frequency Over-Current Fault Monitors by Using Low-Side MOSFET RDS(ON) Output Under-Voltage Protection Applications 16V to 30V Input High Power DC-DC Regulators Low-Voltage Distributed Power Supplies General Description The G5207 provides complete control and protection for a DC-DC converter for high power applications. It is designed to drive two N-channel MOSFETs in a synchronous-rectified buck topology. The G5207 integrates all of the control, and protection functions into a single package. The G5207 provides simple, single feedback loop, voltage-mode control with fast transient response. It includes a 300KHz free-running triangle-wave oscillator. The error amplifier features a 15MHz gain-bandwidth pro...
