SE1052 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) modes.
SE1052 integrates one voltage reference, three operational amplifiers (the outputs are OR’ed together, common collectors), and a current sensing circuit.
The voltage reference, together with one operational amplifier, makes it an ideal voltage controller. The other low voltage reference, together with another operational amplifier, makes it an ideal current limiter for low side output current sensing. The current threshold is fixed, and precise. The third operational amplifier control the Green LED and the Red LED.
The SE1052, housed in space-saving SOP8 package, is ideal for space sensitive applications such as adapters, cellphone chargers, Digital Camera chargers, and other battery chargers.
