ETA1061D2G-电池充电管理芯片
DESCRIPTION
ETA1061 is a high efficiency synchronous step-up converter with ultra-
low quiescent current down to 1μA. It is capable of delivering at least
2W of power from a low voltage source, i.e. 0.4A at 5V output. It also
features a true-shutoff function that disconnects the input from output,
during shutdown and output short-circuit conditions. This eliminates
the need for an external MOSFET and its control circuitry to disconnect
the input from output and provides robust output overload protection.
A switching frequency of 1.4MHz minimizes solution footprint by
allowing the use of tiny and low profile inductors and ceramic
capacitors. An internal synchronous MOSFET provides highest
efficiency and with a current mode control that is internally
compensated, external parts count is reduced to minimal. With the
ultra-low Iq feature, ETA1061 is ideal for solution that requires low
standby power and compact board size such as IoT applications.
