Silergy SY20516A
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. The output voltage can be configured between 2.6V and 3.8V using a resistor divider.| Part No. | SY20516A |

GENERAL DESCRIPTION
Under light load, the part switches automatically to PFM mode to maintain high efficiency. A soft-start circuit limits the power-up inrush current, and can be configured using an external capacitor. A simple RC series compensation network ensures stable operation across the range of loads and input voltages. The device has an IQ of 60 µA (typ.). During shutdown, the load is disconnected from the battery, and the quiescent current is reduced to 0.1 µA (typ.) The SY20516A is designed to supply systems powered by either a two cell or three cell alkaline, Ni-Cd or Ni-MH battery, or a single cell Li-Ion or Li-polymer battery. The device is available in a 3mm3mm DFN package.FEATURES
