MT2011充电IC

The MT2011 is a 4.5-20V input, 2A single-cell synchronous Li-Ion battery switching charger, suitable for portable application. The MT2011 integrates a synchronous PWM controller, 20V rating power MOSFETs, current sense resistor, high-accuracy current and voltage regulation, and charge termination, into a compact 8-pin SOP_EP package.

MT5036升压IC

The MT5036 devices provide a power supply solution for products powered by either a one-cell Li-Ion or Li-polymer battery. The converter generates a stable output voltage that is either adjusted by an external resistor divider or fixed internally on the chip. It provides high efficient power conversion and is capable of delivering output currents up to 3A at 5V with a supply voltage down to 3V. The maximum peak current in the step-up switch is limited to a value of 6.6A. The MT5036 operates at 800kHz switching frequency and enters pulse-skip-mode (PSM) operation at light load currents to maintain high efficiency over the entire load current range. The PSM mode extends the battery life by reducing the quiescent current to 120μA (typ) during light load operation. A low-EMI mode is implemented to reduce ringing when the converter enters the discontinuous conduction mode. The converter can be disabled to minimize battery drain. During shutdown, the load is completely disconnected
