APE1913-3 converter
Advanced Power Electronics, a leading Taiwanese manufacturer of MOS power semiconductors for DC-DC power conversion applications, introduced their latest current mode step-up converter for small, low power applications. The input voltage of the APE1913-3 converter can range from 2.6V to 5.5V, while the output voltage can be adjusted up to 27V. The nominal operating frequency of 1.2MHz enables the use of small external inductors and capacitors and facilitates fast transient response. The internal soft-start results in a small inrush current and extends battery life. An internal power MOSFET with very low on-resistance (Rds(on)) ensures high efficiency.
The APE1913-3 converter automatically switches from PWM to PFM during light load conditions to further increase its efficiency. The device also provides protection functions such as under-voltage lockout, current limit and thermal shutdown. The APE1913TY5-HF-3 is available in a fully RoHS-compliant and halogen-free TSOT-23-5 package.
According to Ralph Waggitt, President/CEO, Advanced Power Electronics Corp. (USA): “This converter includes the popular protection functions such as under-voltage lockout, current limit and thermal shutdown, and is a simple, cost-effective solution for a wide variety of applications.
