Data Sheets:
The MCP16418 is a Boost regulator from the MCP1641X family of low quiescent current boost converters with integrated status indicators and wide input voltage range for a variety of battery powered applications. The regulator provides an automatic input-to-output voltage bypass operation which help in optimizing battery utilization and achieving high efficiency while fresh batteries’ nominal voltage is in the same range with the converter’s output value.
The MCP16418 operates in PWM mode switching at 500 kHz. During periods of light load operation, these devices continue to operate at a fixed 500 kHz switching frequency, allowing pulse skipping. The device can be powered by either single-cell, two-cell alkaline/NiMH batteries or single-cell Li-Ion/Li-Polymer batteries. A low-voltage designed architecture allows the regulator to start up without high inrush current or output voltage overshoot from a low input voltage. The start-up voltage is easily programmed by a resistive divider connected to the UVLO pin. If the resistive divider is not used, the default start-up voltage will be 0.85V. The 0.8V built-in UVLOSTOP helps prevent deep discharge of the alkaline battery, which may cause battery leakage. An open-drain Low Battery Output (LBO) pin will warn the user to replace the battery if the input voltage ramps down to the programmed UVLOSTART value.
The MCP16418 includes Power Good Output (PG) which flags a warning signal when the output level drops below 10% of its nominal value – valuable for devices such as personal care products, Bluetooth headsets and toys.
The device also incorporates the input-to-output bypass shutdown option. With the EN input pulled low, the output is connected to the input using the internal P-Channel MOSFET.
