Beschreibung
ROHM’s high efficiency switching regulator,BD9B331GWZ, is a step-down converter designed toproduce a low voltage output of 0.6V~3.3V from a2.7V~5.5V power supply line. It offers high efficiency inall load ranges by automatic PFM/PWM adjustment. Itemploys an On time control system to provide fastertransient response to sudden change in load.
Eigenschaften
Fast transient response with On time control system. High efficiency for all load range with synchronousrectifier (Nch/Nch FET) and adaptive PFM/PWMsystem. Adjustable Soft-start function. Thermal and UVLO protection. Short-circuit current protection with pulse count Shutdown function.
Typische Anwendungen
- Secondary power supply
- Amusement
- Laptop PC / Tablet PC / Server / LCD TV, Storage Devices (HDD / SSD) / Printer
