SY26501
Description
The SY26501 develops a peak current mode-controlled boost regulator and a high-side driver with accurate current monitor to drive the optical modules. The device operates over a wide input voltage from 2.8V to 5.5V and is capable of generating up to 70V regulated output, a 1×/1.8× dual-gain current mirror with a track and hold output buffer, which is unique to simplify the fiber module circuit design with a MCU with regular resolution ADC.
