Description The HV8211A is a high efficiency, high frequency synchronous
DC-DC step-down converter. The 100% duty cycle feature provides low
dropout operation, extending battery life in portable systems. The internal
synchronous switch increases efficiency and eliminates the need for external
Schottky diode.At shutdown mode, the input supply current is less than 1µA.
The current limit protection and on-chip thermal shutdown features provide
protection against any combination of overload or ambient temperature.
Features ? Low RDS(ON) for Internal Switch (Top/Bottom):
280/200m? ? 2.5V~6V Input Voltage Range ? 1A Output Current ?
1.5MHz Switching Frequency Minimizes the External Components ?
Internal Soft-start Limits the Inrush Current ? Internal Compensation
Function ? 100% Dropout Operation ? RoHS Compliant and Halogen Free
SOT-23-5 Packages
The current limit protection and on-chip thermal
shut down features provide protection against any
combination of overload or ambient temperature.
