Product Overview

The LM63615DQDRRRQ1 is a 3.5V to 36V input, 1.5A output DC/DC buck converter featuring a synchronous rectification architecture, offering high efficiency, low EMI, and a compact size. Its key features include:

Wide input voltage range (3.5V–36V), suitable for automotive battery systems (12V/24V) and industrial power applications.

Integrated spread spectrum modulation to reduce EMI interference, compliant with CISPR 25 standards.

High flexibility, supporting pin-selectable output voltage (3.3V, 5V, or adjustable 1V–20V) and switching frequency (400kHz, 2.1MHz, or adjustable 250kHz–2.2MHz).

Low quiescent current (23µA) for improved light-load efficiency.

Key Features

Automotive-grade certification:

Compliant with AEC-Q100 Grade 1 standards, operating temperature range -40°C to +125°C (ambient temperature), junction temperature up to 150°C.

Provides functional safety documentation, supporting automotive safety standards such as ISO 26262.

Efficient power management:

Synchronous rectification, improving conversion efficiency (up to 95%).

Automatic frequency foldback, optimising light load efficiency.

Protection features: Thermal shutdown, input under-voltage lockout (UVLO), cycle-by-cycle current limit, and intermittent short-circuit protection.

Package options: WSON-12 (3mm × 3mm), suitable for space-constrained automotive electronic designs.

Pin-compatible with LM63610 (1A) and LM63635 (3.25A), facilitating design upgrades or downgrades.
