1 Introduction
The TPS562207 is a single, adaptive on-time, D-CAP2
™
mode, synchronous buck converter requiring a very low
external component count. The D-CAP2 control circuit is optimized for low-ESR output capacitors such as
POSCAP, SP-CAP, or ceramic types and features fast transient response with no external compensation. The
switching frequency is internally set at a nominal 580 kHz and operates in Forced Continuous Conduction Mode
(FCCM). The high-side and low-side switching MOSFETs are incorporated inside the TPS562207 package along
with the gate-drive circuitry. The low drain-to-source on resistance of the MOSFETs allows the TPS562207 to
achieve high efficiencies and helps keep the junction temperature low at high output currents. The TPS562207
dc/dc synchronous converter is designed to provide up to a 2-A output from an input voltage source of 4.3 V to
17 V. The output voltage range is from 0.804 V to 7 V. Rated input voltage and output current ranges for the
evaluation module are given in
.
The TPS562207EVM evaluation module (EVM) is a single, synchronous buck converter providing 1.05 V at 2 A
from 4.3-V to 17-V input. This user’s guide describes the TPS562207EVM performance.
