GENERAL DESCRIPTION
FSP3131 consists of step-down switching
regulator with PWM control.
These devices include a reference voltage source, oscillation circuit, error amplifier and internal PMOS.
FSP3131 provides low-ripple power, high efficiency, and excellent transient characteristics.
The PWM control circuit is able to vary the duty ratio linearly from 0 ...
