Description
STR-A6351A is a hybrid IC designed for fly-back converter type SMPS applications. It is a part of the STR-A6300 series, which is known for its small size and high efficiency. This IC combines a power MOSFET and a controller IC into a single package, making it suitable for small power SMPS designs. The PRC (Pulse Ratio Control) technology provides precise on-width control with fixed off-time.
Specifications and features
- Small sized 8-pin DIP type full molded package
- Oscillator incorporated in the monolithic control IC with on-chip trimming technology
- Small temperature characteristics variation with temperature-compensated control
- Low start-up circuit current (50uA max)
- Built-in active low-pass filter for stable operation at light load
- Avalanche energy guaranteed MOSFET with high VDSS
- Built-in constant voltage drive circuit
- Various protection functions: Pulse-by-pulse Overcurrent Protection (OCP), Overvoltage Protection with latch mode (OVP), Thermal Shutdown with latch mode (TSD)
Application Scenarios
The STR-A6351A is particularly suitable for fly-back converter type SMPS applications that require small size and high efficiency. It can be used in various electronic devices, including but not limited to:
- Power supplies for consumer electronics
- LED lighting
- Battery chargers
