SY20516A
SY20516A is 1.2A Buck-Boost DC/DC Regulator manufactured by Silergy.
High Efficiency, 1MHz，1.2A Buck-Boost DC/DC Regulator
General Description
The SY20516A operates over an input voltage range from 2.6V to 5.5V, and can provide up to 1.2A to the load.
The device uses a 1MHz fixed frequency, pulse-widthmodulation (PWM) architecture to obtain high efficiency, while enabling a small solution size. Under light load, the part switches automatically to PFM mode to maintain high efficiency.
The output voltage can be configured between 2.6V and 3.8V using a resistor divider. A soft-start circuit limits the power-up inrush current, and can be configured using an external capacitor. A simple RC series pensation network ensures stable operation across the...
