TS3300DB: 3V @ 100mA +LDO, 0.6 ~ 4.5V in

Summary

The demo board for the TS3300 is a completely assembled and tested circuit board that can be used for evaluating the TS3300. The TS3300 is a first generation Touchstone Semi power management product that combines a high-efficiency boost regulator and a low dropout linear regulator (LDO) in one package. The TS3300 LDO’s input is connected to the output of the boost regulator, serving as a post-regulator for the boost.

The TS3300 includes an anti-crush(TM) feature to prevent the collapse of the input voltage to the boost regulator when the input is a weak (high impedance) source. If the input voltage drops below a pre-determined voltage threshold (settable by a resistor divider), the boost regulator switching cycles are paused, effectively limiting the minimum input voltage. A pull-down resistor pad is available in order to set the anti-crush(TM) voltage.
