+3A Switching Charger, 2.4A Boost and 3 LED-indicators for battery level, charge/discharge status in One ESOP8 with Single Inductor
9
+
10
+ETA9742 is a switching Li-Ion battery charger capable of delivering up to 3A of charging current to the battery and also capable of delivering up to 5V/2.4A in boost operation, with high efficiency in both charging mode and boost mode. It also includes a fuel gauge system for power indication. For charging, it uses a proprietary control scheme that eliminates the current sense resistor for conventional constant current control, maximizing efficiency, reducing charging time and reducing costs. It can also output a 5V voltage in the reversed direction by boosting from the battery. It only needs a single inductor to provide power bidirectionally with a proprietary automatic mode detect and switch scheme. ETA9742 is an ideal all-in-one solutionfor battery charging and discharge applications, such as power banks, smart phones, and tablets with only one USB port that can be used for charging battery function.
11
+
12
+ETA9742 is suitable for charging a 4.2V Li-ion battery. And ETA9742 is inESOP8 package

15
+A flyback controller is the "brain" of a Flyback Switching Mode Power Supply (SMPS).
16
+
17
+In a flyback topology, a primary switch (usually a MOSFET) turns on and off at high frequencies.
18
+
19
+When the switch is ON: Energy from the input source is stored in the magnetic field of a specialized transformer (coupled inductor).
20
+
21
+When the switch is OFF: The stored energy "flies back" and transfers to the secondary side to power the load.
22
+
23
+The controller's job is to monitor the output voltage via a feedback loop (usually an optocoupler) and precisely modulate the switching of the MOSFET to maintain a steady output voltage, even if the load changes or the input voltage fluctuates.

An SMPS (Switched-Mode Power Supply) is an electronic circuit that efficiently converts electrical power from one form to another, typically changing AC (wall voltage) to regulated DC.
