5V • Adjustable output current limit • Includes full output isolation/reverse current blocking when disabled • 2 MHz ± 10% fixed switching frequency • Low power mode • High efficiency – up to 95% • Full protection for over-current, over-temperature, VOUT over-voltage, and VIN under-voltage • Power good/fault indication Summary Specifications • Ambient operating temperature -40C to 85C • Packaged in a 16pin QFN (3x3) TS32101 High Efficiency DC/DC Boost Converter for USB, 2Mhz Description The TS32101 is a DC/DC synchronous switching Boost Converter with fully integrated power switches, internal PWM current mode compensation, and full fault protection.
The switching frequency of 2 MHz was chosen to enable the use of small external components for portable applications.
The device also has a constant output current limit loop to provide a sharp output current limit that doesn’t move significantly with input voltage and output voltage.
Applications • USB power • Portable products • Wireless remote sensors • Emergency chargers Typical Application Circuit VIN VSW TS32101 CIN ISEN GND LOUT 1 uH RSENSE COUT 2 x 22 uF EN VOUT RTOP RBOT VOUT2 CFF COUT2 PGND FB PG VDD RPULLUP (optional) TS32101 Final Datasheet January 26, 2016 Rev 2.
