Overview
Advanced Power Electronics Corp.
FEATURES Operating Voltage from 2.
6V to 5.
5V Adjustable Output Voltage Range up to 27V Up to 3A Output Switch Current 680K/1.
2MHz Selectable Switching Frequency Programmable Soft-start Function External Compensation Network Current Limit and Thermal Shutdown Protection Under Voltage Lockout < 1µA Shutdown Current Available in the Pb-Free MESOP-10, MESOP-8, TDFN 3x3-10L and ESOP-8 Packages APE1920 DESCRIPTION The APE1920 is a high performance, high efficiency step up DC-DC Converter with integrated 3A.
The APE1920 converter input voltage ranging from 2.
6 to 5.
5V.
The Output voltage can be set up to 27V.
The selectable frequency of 680 kHz and 1.
2 MHz allows the use of small external inductors and capacitors and provides fast transient response.
Current mode control with external compensation network makes it easy to stabilize the system and keep maximum flexibility.
Programmable soft start function minimizes impact on the input power system.
Internal power MOSFET with very low RDS (ON) provides high efficiency.
The APE1920 automatically transits from PWM to PFM during light load condition further increasing efficiency.
The converter also provides protection functions such as Current Limit and Thermal shutdown.
The APE1920 is available in space-saving MESOP-10, MESOP-8, TDFN 3x3-10L and ESOP-8 packages.
