APW7277

APW7277 5V, 5A, 1.2MHz Synchronous Boost Converter Features General Description 92% Effiicency Synchronous Boost Converter With The APW7277 is a synchronous rectifier, fixed switching 1000-mA Output Current From 1.8V Input frequency (1.2MHz typical), and current-mode step-up Stable with Low ESR Output Capacitors regulator. The device allows use of small inductors and Fixed 1.2MHz Oscillator Frequency output capacitors for USB devices. The current-mode Low EMI Converter (Integrated Anti-Ringing control scheme provides fast transient response and Function) good output voltage accuracy. Low Battery Output At light loads, the APW7277 will automatically enter in Pulse Frequency Modulation (PFM) operation to reduce Integrated Power Save Mode Operation to Improve the dominant switching losses. During PFM operation, Light Load Efficiency Load Disconnected During Shutdown the IC consumes very low quiescent current and maintains high efficiency over...
