AS2001-Asynchronous Boost Controller


AS2001-Asynchronous Boost Controller DataSheet

AS2001 10V~12.6V TO 19V 4.7A

General Description
      The AS2001 is a boost topology switching regulator control IC for battery-powered applications. The AS2001 includes a totem-pole single output stage for driving NPN transistor or N-MOS, high precision reference voltage(0.5V) to compare output voltage with feedback amplifier, an internal duty time control for controlling the minimum duty cycle, programmable soft start with short circuit protection function and logic level control for operating mode or standby mode.

Features
 Wide Supply Voltage Operating Range: 1.8 to 15V
 Precision Reference Voltage: 0.5V ±2%
 Low Current Consumption: 5.5mA in Operation Mode
 Low Current Consumption: 1μA in Standby Mode
 High Oscillator Frequency: 1MHz max.
 Totem-Pole Output with Adjustable ON / OFF Current (for NPN Transistors or n Channel MOSFET)
 Logic Level Control Stand-by Mode Function
 Programmable Soft Start Function (SS)
 Short Circuit Protection Function (SCP)
 Package: TSSOP-8L

Applications
 Digital Camera
 PDA
 Portable Equipment
