2.5 MHz efficient boost converter
HL7613
Message
The HL7613 device provides a power supply solution for battery-powered portable applications. Intended for low-power applications, the HL7613 supports up to 1.1A load current from a battery discharged as low as 2.3V and allows the use of low-cost inductor and capacitors.
With a wide input voltage range of 2.3V to 5.5V, the device supports applications powered by Li-Ion batteries with extended voltage range. Different fixed voltage output versions are available from 3.3V to 5.5V.
The HL7613 operates at a regulated 2.5MHz switching frequency and enters power-save mode operation at light load currents to maintain high efficiency over the entire load current range. The PFM mode extends the battery life by reducing the quiescent current to 50μA (typ.) during light load operation.
In addition, the HL7613 device can also maintain its output biased at the input voltage level. In this mode, the synchronous rectifier is current limited allowing external load (e.g. audio amplifier) to be powered with a restricted supply. During shutdown, the load is completely disconnected from the battery. Input current in shutdown mode is less than 1μA (typ.), which maximizes battery life.
The HL7613 offers a very small solution size due to minimum amounts of external components. It allows the use of small inductors and input capacitors to achieve a small solution size.
