HL7509FNQ

The HL7509FNQ is a synchronous buck converter optimized to supply low-voltage applications. Its input voltage range is 2.5-5.5V. Its output voltage range is 0.6-1.23V programmed through an I2C interface. Its output voltage can be adjusted on the fly to provide dynamic voltage scaling (DVS) function with a programmable slew rate. The HL7509FNQ maintains good efficiency for a wide range of load. It delivers a maximum 5A RMS load current while spurious load up to 8A can be supported for 10ms duration. It operates at fixed frequency of 2.4MHz, which reduces the value of the external components. A wide range of output capacitors can be used to optimize VOUT excursion during load transients. The inductors from 0.22μH to 1.0μH may be used without affecting loop stability. At moderate to light load, the pulse frequency modulation (PFM) is used to maintain conversion efficiency with a typical non-switching quiescent current of 70µA. Even with such a low quiescent current, the HL7509FNQ maintains excellent load and line transient responses. At higher loads, the system automatically switches to fixed-frequency pulse width modulation (PWM) operation at for minimum VOUT ripple and optimal load transient response. In shutdown mode, the supply current drops below 1µA and reduces a power consumption. The PFM mode can be disabled if needed through I2C registers.

HL7509FNQ is a synchronous buck converter designed for low-voltage applications. Its input voltage range is from 2.5V to 5.5V and the output voltage range is from 0.6V to 1.23V, programmed via the I2C interface. Its output voltage can be dynamically adjusted to provide dynamic voltage scaling (DVS) functionality at a programmable conversion rate. The HL7509FNQ maintains good efficiency across a wide load range. It provides a maximum RMS load current of 5A, while a pseudo load of up to 8A can be supported for a duration of 10ms. The HL7509FNQ operates at a fixed frequency of 2.4MHz, reducing the value of external components. A wide range of output capacitance can be used to optimize VOUT drift during load transients. Inductors between 0.22μH and 1.0μH can be used without affecting loop stability. In medium to light load conditions, the HL7509FNQ uses pulse frequency modulation (PFM) to maintain conversion efficiency, with a typical non-switching quiescent current of 60µA. Even with such a low quiescent current, the HL7509FNQ still maintains good load and line transient response. Under heavy load conditions, the system automatically switches to fixed frequency pulse width modulation (PWM) operation for minimal VOUT ripple and optimal load transient response. In shutdown mode, the supply current drops below 1μA, reducing power consumption. If needed, the HL7509FNQ can disable PFM mode via the I2C register.
