General description
The AS1170 is an inductive high efficient DCDC step up converter with two current sinks. The DCDC step up converter operates at a fixed frequency of 4 MHz and includes soft startup to allow easy integration into noise sensitive RF systems. The AS1170 includes flash timeout, overvoltage, over temperature, undervoltage and short circuit protection functions. The AS1170 is controlled by an I²C interface and has a hardware automatic shutdown if SCL=0 for 100 ms. Therefore, no additional enable input is required for shutting down of the device once the system shuts down. The AS1170 is available in a space-saving WL-CSP package measuring only 2.25 mm x 1.5 mm x 0.6 mm.
