A 0.6–3.0 V IN, 1.8–3.6 V OUT, 3.5 µA, High-Efficiency Boost +
Output Load Switch
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 power management product
that combines a high-efficiency boost regulator and an output load switch in one pack-
age.
The TS3300 includes an Anti-crush
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 voltage.
The TS3300 boost regulator is set to an output voltage of 3.6 V via a resistor divider cir-
cuit. 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 3×3 mm TQFN package with an ex-
posed back-side paddle. The product data sheet and additional documentation can be
found at www.silabs.com.
