Overview of L4970A by STMicroelectronics
The L4970A designed by STMicroelectronics is a 10 A switching regulator integrated circuit (IC) optimized for voltage mode control. This IC is capable of delivering output currents of up to 10 A with an adjustable output voltage range. The design is encased in a plastic, power pack-15 (ZIP-15) package, making it robust for various applications that require reliable power management. The product is characterized by its flexibility in handling input voltages ranging from 15V to 50V, with an optimal performance around 35V, and supports output voltages nominally set around 5.1 V.
It operates with a pulse width modulation (PWM) control technique, enhancing its efficiency by modulating the width of pulses based on the load requirement. The device boasts a switching frequency of up to 500 kHz, allowing for smaller sized external components and thus reducing the overall board space requirement. Its technology is based on BCDMOS (Bipolar CMOS-DMOS), a process that provides better energy efficiency and improved power handling capability.
With a focus on practicality, the L4970A is not surface mount; it utilizes through-hole technology, favoring applications where mechanical strength and ease of replacement are priorities. The pin arrangement is designed in a zig-zag fashion to optimize the PCB layout. Furthermore, the terminal finish on this component is matte tin (Sn) – annealed, providing good solderability and long-term reliability.
