The full range of AME provides dual protection of over-current protection and thermal shutdown protection to ensure the safety of terminal products. Currently, AME supplies power management solutions for tablet computers and peripheral devices, and its product features are as follows:

DC-DC BUCK Converter:

AME5248/5248A 1.5MHz, 600mA Synchronous Buck Converter:
AME5248/5248A products are 600mA pulse width modulation/pulse frequency modulation synchronous buck DC-DC converters (PWM/PFM Synchronous Buck DC-DC Converters), 100% duty cycle provides low dropout operation, and the highest efficiency can reach 95%. At extremely low loads, AME5248/5248A automatically enters pulse frequency modulation to maintain output voltage regulation, plus 20μA quiescent current and Enable Function to support power saving mode. All of the above features can extend the battery life of portable systems. The fixed 1.5MHz switching frequency allows the use of smaller filter components during design, which is very suitable for thin and compact portable devices. AME5248/5248A provides two modes for customers to choose from: fixed output voltage (1.0~3.3V) and adjustable output voltage (AME5248 is 0.6V~VIN, AME5248A is 0.5V ~ VIN). The operating voltage is 2.5V~5.5V, and the operating temperature is –40°C~125°C.

White LED/OLED Driver:

AME5142/5142A/5142B High Efficiency 6 White LED Driver With Open LED Protection:
The AME5142 series can drive a single string of 1~6 or multiple strings and multiple parallel white LED driver components. It uses a fixed 1.2MHz switching frequency, a current control mode DC/DC boost component, and a built-in N-channel switch to drive 6 series white LEDs. The AME5142 can operate between 2.7V and 5.5V input voltage range, suitable for use in single lithium battery powered applications. The 1.2MHz switching frequency can effectively reduce the size of external inductors and capacitors. Built-in 26V or 28V overvoltage protection function can prevent the load from being unconnected and generating unexpected high voltage. The highest efficiency can reach 88%, and an internal 0.104V reference voltage is provided, which can be used as LED current limiting to obtain the highest efficiency; in addition, AME5142 provides an Enable Function to support power saving mode and extend battery life!
