Product Overview
TPS61220 is a Texas Instruments low input voltage boost converter classified under Power_Management. It operates from a recommended VIN range of 0.7 to 5.5 V and supports startup from 0.7 V with RLoad >= 150 ohm. For the adjustable TPS61220 version, the output voltage range is 1.8 to 6.0 V when VIN is less than VOUT, with a feedback voltage of 483 mV minimum, 500 mV typical, and 513 mV maximum.
The device integrates a main switch and rectifying switch with specified on-resistance values across 3.3 V and 5.0 V output conditions. Electrical performance facts include 0.5% line regulation, 0.5% load regulation, 200 mA inductor current ripple, and switch current limit values up to 400 mA maximum.
TPS61220 is supplied in a 6-pin SC-70 (DCK) package with a 2.00 mm x 1.25 mm body size. Pin functions cover VIN, VOUT, L, GND, EN, and FB. The EN pin must be actively tied high or low, while FB is used for voltage feedback on the adjustable version. Thermal, ESD, shutdown, leakage, and protection ratings are defined in the manufacturer technical datasheet.
