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
