- 产品简介: The HL7227 is a dual phase, up to 98% efficiency and 10V/6A maximum output power switched capacitor down conversion solution. This architecture and the integrated FETs are optimized to enable a 50% duty cycle under CP Mode, CP_FWD allows output voltage VOUT is around half of input voltage WPC/PMID and input current to be half the current delivered to the output, reducing the losses over the input power cable as well as limiting the temperature rise in the application. CP_REV allows output voltage WPC/PMID is around twice of input voltage VOUT and output current to be half of input current. The dual-phase architecture reduces the input cap requirements as well as reducing the input voltage ripple. Besides CP Mode, HL7227 also has BP Mode. BP_FWD allows WPC/PMID forwardly passing through internal power FETs to VOUT without any conversion. BP_REV allows VOUT reversely passing through internal power FETs to WPC/PMID without any conversion. In between PMID and VOUT, HL7227 allows loading current up to 5A. In between WPC and VOUT, HL7227 allows loading current up to 3.0A. HL7227 also supports BP Mode and CP Mode switch automatically switch in forward direction. The switch mode switch threshold is configurable. HL7227 Integrates all the necessary protections to ensure safe operation, including Input UVLO, WPC/PMID OVP, VOUT OVP, PMID to VOUT OVP/UVP, CFLY SCP, Current Limit, OTP etc. HL7227 supports Master-Slave operation for expanding maximum driving capability from 5A to 12A under CP_FWD. The HL7227 is available in a 2.6mm x 2.8mm 36-bump wafer level CSP package.
HL7227 is a dual-phase high-voltage switch capacitor buck converter with a maximum output power of 10V/4.5A and an efficiency of up to 98%. The architecture and integrated FET are optimized to achieve a 50% duty cycle in charge pump (CP) mode. CP_FWD allows the output voltage (VOUT) to be about half of the input voltage (WPC/PMID), with the input current being half of the current delivered to the output, reducing losses in the input power cable and limiting temperature rise in the application. CP_REV allows the output voltage (WPC/PMID) to be approximately twice the input voltage (VOUT), with the output current being half of the input current. The dual-phase structure reduces the requirements for the input cap and input voltage ripple. In addition to CP mode, the HL7227 also features bypass (BP) mode. BP_FWD allows WPC/PMID to pass through the internal power FET to VOUT without any conversion. BP_REV allows VOUT to pass back through the internal power FET to WPC/VMID without any conversion. Between PMID and VOUT, the HL7227 allows load currents of up to 4.5A. Between WPC and VOUT, the HL7227 allows load currents of up to 3.0A. The HL7227 also supports BP and CP modes to automatically switch to the forward direction. The threshold for switching mode is configurable.
