Beschreibung
The STR5A460 Series is power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC for non-isolated Buck converter and Inverting converter topologies.The operation mode is automatically changed, in response to load, to the fixed switching frequency, to the switching frequency control, and to the burst oscillation mode. Thus the power efficiency is improved.The product achieves high cost-performance power supply systems with few external components.
Eigenschaften
- Buck converter
- Inverting converter
- Current mode type PWM control
- Automatically changed operation mode in response to load conditionsFixed switching frequency mode, 60 kHz (typ.)Green mode, 23 kHz (typ.) to 60 kHz (typ.)Burst oscillation mode
- No need for current detection resistor, building in a MOSFET used as current sense resistor
- Built-in Startup Function
- Built-in Error Amplifier
- Random Switching Function
- Leading Edge Blanking Function
- Soft Start Function
- ProtectionsOverload Protection (OLP): Auto-restartOvervoltage Protection (OVP): Auto-restartThermal Shutdown with hysteresis (TSD): Auto-restart
