Buck regulators offer high power density, self-synchronization for PoL
Offer combo of power sequencing, adjustable switching frequency, and clock synchronization options
A line of 10 synchronous buck regulators features high power density and self-synchronization, and provides high-efficiency dc/dc power conversion for PoL power supply designs, applications such as communication, data storage, industrial, and automotive. Part of the company’s PowerWise energy-efficient product family, the highly integrated regulators feature a variety of input voltages and output currents, and offer a combination of power sequencing, adjustable switching frequency, and clock synchronization options.
The LM201xx and LM202xx lines include 2-, 3-, 4-, and 5-A output current devices. Each regulator integrates two switching MOSFETs and uses an externally compensated peak current-mode control loop for load-transient response in low-duty-cycle applications. The regulators are offered in a 16-pin thermally enhanced TSSOP package.
The nine low-voltage buck regulators operate with an input voltage range from 2.95 to 5.5 V and deliver up to 5 A of continuous output current. Both fixed and adjustable switching frequency versions are available.
The high-voltage LM20242 buck regulator, offered in a 20-pin TSSOP with exposed pad, has an input voltage range from 4.5 to 36 V and delivers up to 2 A of continuous output current. It features adjustable frequency from 250 kHz to 1 MHz. (Ea/1,000: From $2.30 to $3 — available now.)
