Key Features
- Wide 3.5V to 36V input range with 2.5A peak output current, covering automotive battery bus voltages including cold-crank and load-dump transients up to 36V
- Integrated spread-spectrum frequency dithering reduces conducted and radiated EMI, simplifying compliance with CISPR 25 Class 5 requirements in automotive infotainment and ADAS systems
- Dual-mode PFM/PWM control technique enables high efficiency at light loads while maintaining tight voltage regulation under heavy transient loads
- 12-pin WSON (S-PDSO-N12) package with exposed thermal pad minimizes PCB area while providing excellent thermal performance for high-density automotive power designs
Applications
The PLM63625DQB1DRRQ1 is designed for automotive applications requiring robust step-down power conversion, including infotainment head units, advanced driver-assistance systems (ADAS), body control modules, and telematics units. Its wide input range and spread-spectrum EMI reduction make it ideal for directly powering microcontrollers, FPGAs, and communication interfaces from the 12V automotive battery bus. The AEC-Q100-qualified device also suits industrial applications where a 36V input range and low EMI are critical.

Frequently Asked Questions
What is the input voltage range and output current capability of the PLM63625DQB1DRRQ1?
The PLM63625DQB1DRRQ1 accepts an input voltage from 3.5V to 36V and delivers up to 2.5A of continuous output current. The nominal input voltage is 13.5V, matching typical automotive 12V battery systems, while the 36V maximum accommodates load-dump transients without external protection.
What does the spread-spectrum feature do in the PLM63625DQB1DRRQ1?
The spread-spectrum feature dithers the switching frequency over a defined range, spreading the switching noise energy across a wider frequency band rather than concentrating it at a single frequency. This significantly reduces peak EMI emissions, making it easier to meet automotive EMC standards such as CISPR 25 Class 5 without requiring large external filters.
What package does the PLM63625DQB1DRRQ1 use?
The PLM63625DQB1DRRQ1 comes in a 12-pin WSON (Wafer-Scale Small Outline No-Lead) package with JESD-30 code S-PDSO-N12. The package features an exposed thermal pad on the bottom for efficient heat dissipation. The tape-and-reel suffix (DRRQ1) indicates 3,000-unit automotive-grade reels for high-volume manufacturing.
Is the PLM63625DQB1DRRQ1 AEC-Q100 qualified for automotive use?
Yes, the 'Q1' suffix in PLM63625DQB1DRRQ1 indicates AEC-Q100 automotive qualification. It is designed to meet the reliability and temperature requirements of automotive Grade 1 applications, operating reliably across the full automotive temperature range and withstanding the electrical stresses typical of vehicle power systems.
Can the PLM63625DQB1DRRQ1 output a fixed 5V or an adjustable voltage?
Yes, the PLM63625DQB1DRRQ1 supports both a fixed 5V output and an externally adjustable output voltage, as noted in its specification ('ALSO HAS 5V FIXED O/P VOLTAGE'). The adjustable output is set using a resistor divider on the feedback pin, giving designers flexibility to power different voltage rails from a single converter.
