TS32101
Version 2.0
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
 Battery-powered chargers for portable
equipment
 Compatible with Ni-MH, Ni-Cd, Li-Ion
