产品概述
描述
POLAR06 is part of a family of 2 A, 4 A and 6 A synchronous step-down DC-DC converters based on a peak current mode control topology. The PoLAR family is designed to support automotive applications.
Low resistive switches allow up to 6 A continuous output current at high ambient temperature. For systems with higher power requirements, a multiphasing parallel converter is readily implemented.
The switching frequency is externally adjustable in 4 steps, 1.8 MHz, 2.25 MHz, 3.26 MHz and 4 MHz, and can also be synchronized to an external clock in a continuous way in the same frequency range. In PWM/PFM mode, the POLAR06 automatically enters power Save mode at light loads to maintain high efficiency across the whole load range.
The POLAR06 provides 1% output voltage accuracy, which helps design a power supply with high output voltage accuracy.
The soft start limits the inrush current during startup.
The PoLAR family comes in a bondless 3x3 mm package, with wettable flanks.
