SY20011 - 1MHz Synchronous Buck Converter

Key Features

  • The SY20011 high-efficiency 1MHz synchronous Buck converter operates over a wide input voltage range from 2.5V to 5.5V and is capable of delivering up to 500mA output current. It integrates a top FET and a bottom FET with very low RDS(ON) to minimize conduction loss. The SY20011 adopts a constant on-time and ripple-based control strategy to achieve fast transient responses. The input and output capacitors, the inductor, and the resistor-divider components must be selected for the targeted appli.

SY20011 400nA Low IQ, 5.5V, 500mA, 1MHz Synchronous Buck Converter General Description Features The SY20011 high-efficiency 1MHz synchronous Buck converter operates over a wide input voltage range from 2.5V to 5.5V and is capable of delivering up to 500mA output current. It integrates a top FET and a bottom FET with very low RDS(ON) to minimize conduction loss. The SY20011 adopts a constant on-time and ripple-based control strategy to achieve fast transient responses. The input and output capacitors, the inductor, and the resistor-divider components must be selected for the targeted application specifications. The device uses only 400nA quiescent current (typ, STB=0) and only 10nA (typ.) in shutdown mode.
