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
