HL7593

HL7593 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 range is 0.600V to 1.394V in 6.25mV steps, 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. HL7593 can deliver up to 86% efficiency 3A output current and maintain over 80% efficiency at 10mA or higher light load currents. It operates at fixed frequency of 2.4MHz, which reduces the value and size of the external components. A wide range of output capacitors can be used to optimize output load transient performances. Inductors from 0.24uH to 1.0uH may be used without affecting loop stability. For maximum 3A output load, Inductors from 0.33uH to 1.0uH is recommended. At moderate to light loads, Pulse Frequency Modulation (PFM) is used to maintain conversion efficiency with a typical non-switching quiescent current of 48µA. Even with such a low quiescent current, HL7593 maintains excellent load and line transient responses. At higher loads, the system automatically switches to fixed-frequency Pulse Width Modulation (PWM) operation at 2.4MHz for minimum VOUT ripple and optimal load transient response. In Shutdown Mode, the supply current drops below 1µA, reducing power consumption. PFM Mode can be disabled if needed through I2C registers. HL7593 supports VOUT remote sensing. It's feedback signal VOUT can be connected close to the power supply pin of the load for a true point-of-load operation without affecting control loop stability. The HL7593 is available in a 15-bump, 0.4mm pitch, 2.01mm x 1.21mm WLCSP.

HL7593 is a synchronous buck converter optimized to power portable applications for different systems. Its input voltage range is from 2.5V to 5.5V. Its output voltage range is from 0.600V to 1.394V, with a step size of 6.25mV, and it is programmed via the I2C interface. Its output voltage can be dynamically adjusted to quickly provide dynamic voltage scaling (DVS) functionality with a programmable conversion rate. HL7593 can deliver an output current of 3A with an efficiency of up to 86%, while maintaining over 80% efficiency when the load current is above 10mA. It operates at a fixed frequency of 2.4MHz, which reduces the values and sizes of the external inductors and capacitors used. It can utilize various output capacitors to optimize the transient performance of the output load. Inductors ranging from 0.33µH to 1.0µH can be used without affecting loop stability. Under moderate and light load conditions, pulse frequency modulation (PFM) is used to maintain conversion efficiency, with a typical non-switching quiescent current of 48µA. Even with such a low quiescent current, HL7593 maintains excellent load and line transient response. Under heavy load conditions, the system automatically switches to a 2.4MHz fixed frequency pulse width modulation (PWM) mode to achieve minimal VOUT ripple and optimal load transient response. In shutdown mode, the supply current drops to below 1µA to reduce power consumption. If needed, PFM mode can be disabled via the I2C register. HL7593 supports remote sensing of VOUT. Its feedback signal VOUT can be connected close to the power pins of the load to achieve true load point operation without affecting the stability of the control loop.
