APW7212CTI-TRG

APW7212 1MHz, High-Efficiency, Step-Up Converter with Load Disconnection Features General Description • Wide 0.8V to VOUT Input Voltage Range • Low 1.05V (typical) Start-Up Voltage The APW7212 is a synchronous rectifier, fixed switching frequency (1MHz typical), and current-mode step-up • Low 40µA No Load Bias Current • 100mA Output from a Single AA Cell Input • 250mA Output from a Dual AA Cell Input • Internal Synchronous Rectifier regulator. The device allows use of small inductors and output capacitors for portable devices. The current-mode control scheme provides fast transient response and good output voltage accuracy. At light loads, the APW7212 will automatically enter in pulse frequency modulation(PFM) operation to reduce • Up to 92% Efficiency •
