EMH7023-500mA,500KHz PWM Synchronous Boost Converter with Output Isolated During Shutdown DataSheet
The EMH7023 is a high efficiency, synchronous fixed frequency, current-mode step-up DC/DC converter. During shutdown mode, the output is completely isolated from the input without drawing any battery current. The fixed 500KHz switching frequency obtains maximum efficiency up to 96% and uses only a few external components.
With 180Ω loading, the minimum start-up voltage can be as low as 0.93V, provided by a one or two-cell alkaline or one-cell Li-Lon battery.
The features of EMH7023 include current limit, low battery comparator, open-drain power good output, short circuit, and thermal shutdown protection. The EMH7023 is also available in E-MSOP-8L package.
