AEC-Q100 Compliant, Automotive Integrated-Coil Step-down “micro DC/DC” Converters
The XDL601/XDL602 series consist of ultra-compact step-down DC/DC converters with integrated coils and control ICs. Simply adding two ceramic capacitors to their external components can make it possible to create a power supply circuit with a maximum of 1.5A, and a 50% or greater reduction in space compared to structures using stand-alone DC/DC converters. Since the coil is built-in, board layouts can be simplified to minimize malfunctions, noise, and other problems arising from component placement or wire routing.
The input voltage can range from 2.5V – 5.5V and the output voltage from 0.8V – 3.6V (standard voltage settings exist), with a switching frequency of 3.0MHz and a circuit system which employs synchronous rectification. The operating mode uses “HiSAT-COT (*) control” which has outstanding transient response characteristics, and allows either “PWM control” or “PWM/PFM automatic switching control” to be selected depending on the application. “PWM control” is capable of suppressing output ripple voltage to a low level, while “PWM/PFM automatic switching control” can achieve high efficiency over all load ranges from light to heavy loading.
Their package is an ultra-compact DFN3625-11B (3.6 x 2.5 x h1.6mm) which uses a wettable flank structure . Fillets are formed at the sides of the terminal, allowing automatic visual inspections of solder joints to be performed.
(*)HiSAT-COT is a proprietary high-speed transient response technology which Torex developed and the DC / DC converters with HiSAT-COT technology are ideal for LSI's that require high precision and high stability power supply voltage.
