The MAX8569A/MAX8569B low-quiescent-current boost regulators provide up to 200mA at output voltages up to 5.5V from a 1.5V to 5.5V input source. The built-in synchronous rectifier allows for over 90% efficiency while achieving small size and low cost by eliminating the need for an external Schottky diode.

The MAX8569A provides an adjustable output while the MAX8569B is fixed at 3.0V or 3.3V. The MAX8569B features a power-on reset output (active-low RST) to signal that the output has reached regulation. All devices connect the battery input to the output during shutdown, allowing the input battery to be used as a backup or real-time clock supply when the converter is off.

Applications

  • Battery Backup
  • Cordless Phones
  • Digital Cameras
  • Local 3.3V to 5V Supplies
  • Medical Diagnostic Equipment
  • PC Cards
  • PDAs and Smartphones

Product Detail

The MAX8569 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board demonstrating the MAX8569A or MAX8569B 200mA step-up boost converter. The EV kit comes with the MAX8569B installed. The application circuits provide a 3.3V output voltage capable of sourcing a maximum of 200mA load current from a 1.5V to 5.5V input source. The MAX8569 features internal MOSFETs to reduce cost and size. It also includes skip mode, which optimizes efficiency at light loads to improve battery life. The MAX8569 EV kit can also be used to evaluate the MAX8569A and MAX8569B30 with minor PCB modification.
