HM6313 - Step-up DC-DC Converter

Key Features

  • The HM6313 is a highly efficient fix frequency synchronous step-up DC/DC converter. Output voltage of the device is adjustable. Power dissipation during operation is only 40μA typical and drops to less than 1μA in shutdown. The 0.85V to 5V input voltage range makes the HM6313 ideally suitable for single cell Li-ion battery, single or dual AA battery voltage step-up.

HM6313 High Efficiency Low Voltage Synchronous Step-up DC/DC Converter GENERAL DESCRIPTION FEATURES The HM6313 is a highly efficient fix frequency synchronous step-up DC/DC converter. Output voltage of the device is adjustable. Power dissipation during operation is only 40μA typical and drops to less than 1μA in shutdown. The 0.85V to 5V input voltage range makes the HM6313 ideally suitable for single cell Li-ion battery, single or dual AA battery voltage step-up applications. Automatic PFM Mode operation increases efficiency at light loads, further extend battery life. Switching frequency is internally set at 1.2MHz, design for use of small value surface mount inductor, input and output capacitors. The internal synchronous switches enhance efficiency.
