SY20492 High-Efficiency 2A Valley-Current Synchronous Boost Converter

SY20492 Description

SY20492 1.8V Minimum Input, 5.5V Maximum Output, High-Efficiency 2A Valley-Current Synchronous Boost Converter General .
The SY20492 is a high-efficiency, synchronous Boost converter designed for single-cell lithium (Li-ion or Li-polymer) or two-cell to three-cell nickel.

SY20492 Features

* 1.8V Minimum Input Voltage
* Adjustable Output Voltage from 1.8V to 5.5V
* Minimum 2A Valley Current Limit
* 5µA Typical Quiescent Current
* Load Disconnect During Shutdown
* Low RDS(ON) at 3.3V Output: 100mΩ Main, 170mΩ Synchronous
* Output Overvoltage Protection (OVP)

SY20492 Applications

* It can operate down to 1.8V input voltage. It uses NMOS for the main switch and PMOS for the synchronous switch. The SY20492 disconnects the output from the input during shutdown mode. When the input voltage exceeds the regulated output voltage, the SY20492 will enter bypass mode automatically. The
