SPF8201
Package：HSOP40
The SPF8201 is power IC for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC. The IC is suitable for switching power supply such as flyback circuit. The IC has a high accuracy error amplifier and provides a stable output voltage.
When the load of the power supply circuit becomes light, the operation of IC becomes the burst oscillation mode in order to improve the circuit efficiency.
By employing the primary-side regulation, the IC realizes low component counts and design-friendliness, leading to downsizing and standardization of the power supply circuit.
