The TMI5111 is a dying gasp storage and release controller IC with internal power MOSFET and Diode. It offers a very compact solution to reduce the storage capacitor and keep the same release time when input is power off. During normal power on, it boosts input voltage and charges storage capacitor with a limited current about 300mA. When the charge voltage reaches the selected voltage set by FB1, the charge is stopped and the voltage is maintained until the low input voltage is detected, which is set by FB2. The TMI5111 release charge form storage capacitor to input capacitor with a limited current about 2A. The storage and release voltage can be programmed by user different external divided resistors of FB1 pin and FB2 pin.
The TMI5111 requires a minimal number of readilyavailable, standard, external components and is available in a SOP8 package.
