Expanded Family of 18V Synchronous DC DC Buck Converters from Diodes Incorporated

Diodes Incorporated announces the AP62xxx, a family of high-efficiency synchronous step-down DC-DC converters now includes the AP62150 (1.5A), AP62200 (2A), AP62201 (2A), and AP62200T (2A). The devices operate from a 4.2V to 18V input voltage range supporting 5V to 12V power rails.

All members of the family have an adjustable output voltage range of VREF to 7V, where VREF is 0.763V for the AP62200T and 0.8V for the other parts. The AP62150 has a higher 1.3MHz operating switching frequency whereas all others have switching frequencies at 750kHz.

The AP62201 operates only in PWM mode regardless of load. The other members of this family operate in PFM at light loads to increase efficiency.

These buck converters include a full protection feature set that make the system more robust. This includes overcurrent protection, under-voltage lockout, and thermal shutdown.

The AP62200T is available only in the TSOT26 package. All other devices are pin-compatible with each other and are available in both the SOT563 and TSOT26 packages.
