A synchronous buck converter can supply large currents with the least amount of power loss and generates a regulated voltage that is lower than its input voltage. The synchronous buck converter is made up of two power MOSFETs, an output inductor, and an output capacitor.
A dual buck controller with a broad operating range of 3.75V to 42V is the ISL78264. It is made to accommodate switching frequencies with a wide duty cycle between 200 kHz and 2.2 MHz. It offers synchronization to an outside clock or programmable spread spectrum clocking to reduce EMI.
Severe line transients are perfectly tolerated by its current-mode modulator. Additionally, to function during automotive cranking and load dump pulses, the ISL78264 supports dropout operation and low 25ns on-time.
The global automotive dual synchronous buck controller market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Dual Synchronous Buck Controllers from Renesas Electronics, model number ISL81802, can produce two separate outputs or one output with two interleaved phases. Peak current mode control and phase interleaving for the two outputs are features of these controllers. Additionally, the ISL81802 controllers have accurate threshold enable and programmable soft-start functions, as well as a power-good indicator that makes power supply rail sequencing easier.
These controllers provide a customizable frequency range of 100 kHz to 1 MHz, a 4.5V to 80V input voltage range, and a low shutdown current of 5A. For excellent dependability, the ISL81802 controllers offer average and peak current limits at both outputs, over- and under-voltage protection, one-time programmable memory, and OTP. These controllers are used in telephony, data centers, automobile electronics, industrial machinery, and power systems, among other applications.
