1.2MHz, Low-Cost,
High-Performance Chargers
The MAX17005B/MAX17006B/MAX17015B include all
the functions necessary to charge Li+, NiMH, and NiCd
batteries. An all n-channel synchronous-rectified step-
down DC-DC converter is used to implement a preci-
sion constant-current, constant-voltage charger. The
charge current and input current-limit sense amplifiers
have low-input offset errors (250µV typ), allowing the
use of small-value sense resistors.

The MAX17005B/MAX17006B/MAX17015B use a new
thermally optimized high-frequency architecture. With this
new architecture, the switching frequency is adjusted to
control the power dissipation in the high-side
MOSFET. Benefits of the new architecture include
reduced output capacitance and inductance, resulting in
smaller PCB area and lower cost.
