STMicroelectronics Buck Boost Switching Regulator 61V HTSSOP 16-Pin A7987TR

STMicroelectronics A7987TR buck boost switching regulator combines flexibility and efficiency in power management applications requiring wide input voltage ranges from 4.5 V to 61 V and output current up to 4 A DC. The device is enclosed in a 16-pin HTSSOP surface mount package with a compact form factor (5.1 mm length x 4.5 mm width x 1.05 mm height), making it suitable for space-constrained industrial and automotive electronics.

This positive polarity regulator supports adjustable switching frequency between 250 kHz and 1.5 MHz, allowing designers to optimize efficiency and electromagnetic interference (EMI) across varying load conditions. The device features a low quiescent current of 3 mA typical, enabling energy-efficient operation, with an ultra-low shutdown current (IQ-SHD) of 11 μA from VIN.

The output voltage can be configured from a minimum of 0.8 V up to the input voltage level, providing precise regulation for a variety of system voltage requirements. The maximum operating temperature rating of 150°C and compliance with the AEC-Q100 automotive standard ensure robust performance in harsh automotive and industrial environments.

This regulator is suited for power management in industrial automation systems, automotive electronics, consumer electronics, and other embedded systems requiring stable voltage beyond conventional regulator limits. Its surface mount HTSSOP package facilitates automated PCB assembly processes while maintaining excellent electrical characteristics with typical RDS(on) of 250 mΩ.

Operates over input voltage range 4.5 V to 61 V wide supply capability. Delivers continuous 4 A DC output current with efficient regulation. Adjustable switching frequency from 250 kHz to 1.5 MHz enhances flexibility. Features low quiescent and shutdown currents for energy savings.

Compact HTSSOP 16-pin surface mount package for space-saving designs. Complies with automotive quality standard AEC-Q100 for reliability. Maximum operating temperature rating of 150°C suitable for industrial use.
