Product Overview

AS1170-ZWLM is an inductive high efficient DC-DC step up converter with two current sinks. The DC-DC step up converter operates at a fixed frequency of 4MHz and includes soft startup to allow easy integration into noise sensitive RF systems. It includes flash timeout, overvoltage, over temperature, undervoltage and short circuit protection functions. It is controlled by an I²C interface and has a hardware automatic shutdown if SCL=0 for 100ms. Therefore no additional enable input is required for shutting down of the device once the system shuts down. It is used in applications such as flash/torch/video light for smartphones, feature-phones, 3D sensing – active stereo vision/structured light, handheld scanners, safety signage.
  • High efficiency 4MHz fixed frequency DC-DC boost converter, stable even in coil current limit
  • Independent channel control, combine channels for higher current output
  • PWM operation for lower output current, 31.25KHz to avoid audible noise
  • Automatic current adjustment for low battery voltage, long battery lifetime
  • 31.25KHz to avoid audible noise, long battery lifetime
  • Current adjustable up to 2000mA, supply voltage range from 3.7V typical
  • Shutdown current is 0.6µA typical at (SCL=SDA=0V, VVIN3.7V)
  • On-resistance is 70mohm typical at (DC-DC internal PMOS switch)
  • Operating frequency is 4MHz typical
  • Operating temperature range from -30°C to 85°C
