The ML4861 is a boost regulator designed for DC to DC conversion in 1 to 3 cell battery powered systems. The combination of BiCMOS process technology, internal synchronous rectification, variable frequency operation,and low supply current make the ML4861 ideal for 1 cell applications. The ML4861 is capable of start-up with input voltages as low as 1V and is available in 6V, 5V, and 3.3V output versions with output voltage accuracy of ±3%.
An integrated synchronous rectifier eliminates the need for an external Schottky diode and provides a lower forward voltage drop, resulting in higher conversion efficiency. In addition, low quiescent battery current and variable frequency operation result in high efficiency even at light loads. The ML4861 requires only one inductor and two capacitors to build a very small
regulator circuit capable of achieving conversion efficiencies in excess of 90%.
The circuit also contains a RESET output which goes low when the IC can no longer function due to low input voltage, or when the DETECT input drops below 200mV.
