HL7504

HL7504 is a synchronous buck converter optimized to supply different sub systems of portable applications. Its input voltage range is 2.5V to 5.5V. Its output voltage is a factory pre-set value between 1.05V and 3.3V. HL7504 can deliver up to 2.0A with 80% efficiency, while maintaining over 80% efficiency at load currents as low as 10mA. It operates at a high frequency of 3MHz, which greatly reduces the value of the external components. A wide range of output capacitors can be used to optimize VOUT stability during load transients. Inductors from 1.0uH to 2.2uH may be used without affecting loop stability. At moderate to light loads, Pulse Frequency Modulation (PFM) is used to maintain conversion efficiency with a typical non-switching quiescent current of 60µA. Even with such a low quiescent current, HL7504 maintains excellent load and line transient responses. At higher loads, the system automatically switches to fixed-frequency Pulse Width Modulation (PWM) operation at 3MHz for minimum VOUT ripple and optimal load transient response. In Shutdown Mode, the supply current drops below 1µA, reducing power consumption. The HL7504 is available in 2 x 2mm DFN-6 Package.

HL7504 is a synchronous buck converter developed specifically for the different core power system requirements of portable product applications. Its input voltage range is from 2.5V to 5.5V. The output voltage is preset from 1.05V to 3.3V. The HL7504 can provide up to 2.0A of current with an efficiency of 80%, while maintaining over 80% efficiency at load currents as low as 10mA. It can operate at a high frequency of 3MHz, thereby reducing the values of external inductors and capacitors used. Additional output capacitance can be added to improve load transient response without affecting VOUT stability. At the same time, inductors ranging from 1.0μH to 2.2μH can be used without compromising loop stability. Under moderate and light load conditions, the HL7504 uses pulse frequency modulation (PFM) to maintain conversion efficiency, with a typical non-switching static current of 60µA. Even with such a low static current, the HL7504 still maintains excellent load and line transient response. Under heavy load conditions, the system automatically switches to 3MHz fixed frequency pulse width modulation (PWM) operation to achieve minimal VOUT ripple and optimal load transient response. In shutdown mode, the power supply current drops to below 1μA, thereby reducing power consumption.
