Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.
The TPS40200 is a flexible nonsynchronous controller with a built-in 200-mA driver for P-channel FETs. The
circuit operates with inputs up to 52 V, with a power-saving feature that turns off driver current once the external
FET has been fully turned on. This feature extends the flexibility of the device, allowing it to operate with an
input voltage up to 52 V, without dissipating excessive power. The circuit operates with voltage-mode feedback
and has feed-forward input-voltage compensation that responds instantly to input-voltage change. The integral
700-mV reference is trimmed to 2%, providing the means to accurately control low voltages. The TPS40200 is
available in an 8-pin SOIC, and supports many of the features of more complex controllers. Clock frequency,
soft start, and overcurrent limit each are easily programmed by a single, external component. The part has
undervoltage lockout, and can be easily synchronized to other controllers or a system clock to satisfy
sequencing and/or noise-reduction requirements.
