AP63200/AP63201/AP63203/AP63205
3.8V TO 32V INPUT, 2A LOW IQ SYNCHRONOUS BUCK WITH ENHANCED EMI REDUCTION Description Pin Assignments The AP63200/AP63201/AP63203/AP63205 is a 2A, synchronous
buck converter with a wide input voltage range of 3.8V to 32V and
fully integrates a 125mΩ high-side power MOSFET and a 68mΩ lowside power MOSFET to provide high-efficiency step-down DC/DC
conversion. TOP VIEW The AP63200/AP63201/AP63203/AP63205 device is easily used by
minimizing the external component count due to its adoption of peak
current mode control along with its integrated compensation network.
The AP63200/AP63201/AP63203/AP63205 has optimized designs for
Electromagnetic Interference (EMI) reduction. The converter features
Frequency Spread Spectrum (FSS) with a switching frequency jitter of
±6%, which reduces EMI by not allowing emitted energy to stay in any
one frequency for a significant period of time. It also has a proprietary
gate driver scheme to resist switching node ringing without sacrificing
MOSFET turn-on and turn-off times, which further erases highfrequency radiated EMI noise caused by MOSFET switching. FB 1 6 BST EN 2 5 SW VIN 3 4 GND TSOT26 The device is available in a low-profile, TSOT26 package. Features Applications • VIN 3.8V to 32V •
