- 产品简介: The HL7612 device provides a power supply solution for battery-powered portable applications. Intended for low-power applications, the HL7612 supports up to 1.0A load current from a battery discharged as low as 2.5V and allows the use of low-cost inductor and capacitors. With a wide input voltage range of 2.5 V to 5.5 V, the device supports applications powered by Li-Ion batteries with extended voltage range. Different fixed voltage output versions are available from 3.8V to 6.0 V. The HL7612 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 22μA (typ.) during light load operation. In addition, the HL7612 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 HL7612 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.
The HL7612 device provides a power solution for battery-powered portable applications. It is suitable for low-power applications, supporting load currents of up to 1.0A even when the battery discharges to as low as 2.5V, and allows the use of low-cost inductors and capacitors. The HL7612 has a wide input voltage range of 2.5V to 5.5V, supporting applications powered by lithium-ion batteries (including extended voltage ranges). Different fixed voltage output versions support voltage ranges from 3.8V to 6.0V. The operating frequency of the HL7612 is 2.5MHz, entering power-saving mode under light load currents to maintain high efficiency across the entire load current range. The PFM mode reduces the static current to 22μA (typical) during light load operation, thereby extending battery life. Additionally, the HL7612 device can maintain its output bias at the input voltage level. In this mode, the current of the synchronous rectifier is limited, allowing external loads (such as audio amplifiers) to be powered by a constrained power source. In shutdown mode, the load is completely disconnected from the battery. The input current in shutdown mode is less than 1μA (typical), maximizing battery life. Due to the minimal number of external components, the HL7612 offers an extremely small solution size. It allows the use of small inductors and input capacitors to achieve a compact solution size.
