Description
The FAN2103 TinyBuck™ is an easy-to-use, cost- and
space-efficient, synchronous buck solution. It enables
designers to solve high-current requirements in a small
area with minimal external components.
External programming of clock frequency, current limit,
and loop response allows for optimization and flexibility
selecting output filter components and transient response.
The summing current mode modulator uses lossless
current sensing for current feedback and over-current,
and includes voltage feedforward.
Fairchild’s
advanced
BiCMOS
power
process,
combined with a thermally efficient MLP package,
provides low-RDS(ON), internal MOSFETs, and the ability
to dissipate high power in a small package.
Under-voltage, thermal shutdown, and power-good are
blanked at start-up, but protect the device from damage
during fault conditions.
