TS3312DB

SILICON LABS  TS3312DB  EVAL BRD, LOW POWER BOOST CONVERTER 新

The is a boost converter demo board for 165nA IQ, instant-on boost converter with 1.9V UVLO threshold. This is a low power boost converter with an industry leading low quiescent current of 165nA, enabling ultra long battery life in systems running from a variety of battery sources. It includes two output options, one being an always-on storage output while the additional output is an output load switch that is designed to burst-on loads in a low duty cycle manner. The output voltage can be set via jumpers S0, S1 and S2. Both the STORE and OUT output can be monitored along with power good output VGOOD. Jumper OUT_ON is available to disable or enable the OUT output. The demo board is configured for 3V output by default and provides test points to monitor output voltage STORE and OUT. The power good pin, VGOOD is pulled to STORE output by a 3.3Mohm pull-up resistor R1, can be monitored via test point PG.
