A 5V power supply that drives an external N-channel FET results in ultra-low saturation with a remarkably low input/output voltage difference of 300mA (max. when Io = 10A). Power loss is minimized by lowering the input voltage, making it ideal for lower voltage PC chipsets.

Original control technology is utilized for the industry's best responsiveness. Suppresses voltage fluctuations and provides stable power supply to low voltage PC chipsets.

Conventional A Class power supplies often exhibit high saturated voltage and considerable heat generation during high current flow - reasons why switching power supplies are often used. However, ROHM offers a more efficient solution with its lineup of ultra-low saturation power supply controllers, featuring low heat generation (high efficiency) even during high current dray several Amperes). Additional advantages include a reduction in the number of parts required along with mounting area.

Original low voltage drive processes are used for stable operation at V_GS = 1.5V. ON-resistance is greatly reduced compared to conventional 2.5V drives - from 20% to 85%.

Hall ICs enjoy widespread use due to their high sensitivity and low power consumption. ROHM utilizes Hall ICs not for constant sensing, but for detection within a fixed period, resulting in a current consumption of only 5µA (typ.). In addition, CMOS output minimizes power consumption during magnetic detection.

Mobile printers have stringent voltage and current limits.Cutting-edge LSI mounting technologies has enabled ROHM to develop more compact, lighter printheads featuring top-shelf energy savings and can be driven with a single lithium ion battery cell (2.7V).

3.3V input interface allows direct drive from an ASIC, simplifying set design while enabling compatibility with common power supplies, contributing to increased energy savings.
