Key Featrues
Low Quiescent Current (IQ): The MAX20030/MAX20031 ICs feature a low quiescent current of 17µA with the 3.3V buck regulator enabled, 25µA with the 5V buck or LDO enabled, and 65µA with all controllers active. This significantly enhances power efficiency, making the device ideal for automotive applications where minimizing power consumption is critical, such as during engine stop-start or cold-crank conditions.
Cold-Crank Operation Support: The integrated preboost controller ensures that the output voltages (VOUT1 and VOUT2) remain regulated even during cold-crank conditions, with input voltages as low as 2V. This feature ensures reliable performance in automotive environments, where battery voltage can drop significantly during engine cranking.
EMI Reduction Features: The ICs include EMI reduction features such as forced fixed-frequency PWM operation, resistor-programmable frequency (220kHz to 2.2MHz), and pin-selectable spread spectrum. These features minimize electromagnetic interference, making the device suitable for use in sensitive applications like navigation and radio head units without compromising the wide input voltage range.
High Integration and Compact Design: The device integrates dual 2.2MHz step-down controllers, a synchronous boost controller, and a high-voltage 200mA LDO in a thermally enhanced 7mm x 7mm, 48-pin TQFN package. This high level of integration saves board space and reduces system cost, making it ideal for compact automotive and industrial applications.
Robust Protection Features: The ICs include supply overvoltage and undervoltage lockout, overtemperature protection, and short-circuit protection. These features enhance system reliability and safety, ensuring the device operates within safe limits even in harsh automotive environments.
