Asynchronous Boost Controller
SX1302
General Description
The SS5X1133092isisaabobosotstotpooploolgoygyswswitcithcihnigngrergeuglualator control IC for battery-powered applications.
The SX1302 includes a totem-pole single output st age 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
