TS32101

TRIUNE PRODUCTS Features Output up to 1.5A at 5.0V with 1.8V input Wide input voltage range: 1.75V – 5.5V Output current up to 2A Robust operation during hot-load disconnect and hot- load disable Adjustable output voltage up to 5.5V 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.
