Description
The FAN2106 TinyBuck⢠is a highly efficient, small-
footprint, constant-frequency, 6A, integrated
synchronous buck regulator.
The FAN2106 contains both synchronous MOSFETs
and a controller/driver with optimized interconnects in
one package, which enables designers to solve high-
current requirements in a small area with minimal
external components. Integration helps to minimize
critical inductances, making component layout
simpler and more efficient compared to discrete
solutions.
The FAN2106 provides for external loop
compensation, programmable switching frequency,
and current limit. These features allow design
flexibility and optimization. High-frequency operation
allows for all-ceramic solutions.
The summing current-mode modulator uses lossless
current sensing for current feedback and over-current
protection. Voltage feedforward helps operation over
a wide input voltage range.
Fairchildâs advanced BiCMOS power process,
combined with low-RDS(ON) internal MOSFETs and a
thermally efficient MLP package, provide the ability to
dissipate high power in a small package.
Output over-voltage, under-voltage, over-current, and
thermal shutdown protections help protect the device
from damage during fault conditions. FAN2106
prevents pre-biased output discharge during startup
in point-of-load applications.
