DESCRIPTION

The TS3300 is a 1st-generation Touchstone Semi power management product that combines a high-efficiency boost regulator and an output load switch in one package. The boost regulator operates from a supply voltage as low as 0.6V and can deliver at least 75mA at 1.2VBI to 3VBO, an industry first.

The TS3300 also includes an anti-crush™ 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 determined voltage threshold (user-settable by an external resistor divider), the boost regulator switching cycles are paused, effectively limiting the minimum input voltage. The TS3300’s anti-crush™ feature is useful in applications where a buffer capacitor at the boost’s output can service burst loads, and the input source exhibits substantial source impedance (such as with an old battery or at cold temperatures).

The TS3300 is fully specified over the -40°C to +85°C temperature range and is available in a low-profile, thermally-enhanced 16-pin 3x3mm TQFN package with an exposed back-side paddle. For best results, the back-side paddle should be soldered to PCB ground.
