36V input, 600mA, Synchronous, Step-down Switching Regulator
Requirement of 24/12V industrial equipment, home facilities, sensors
- 24V ―step-down― 5.0V
Downsizing step-down circuit
- High efficiency
for saving energy
- Lower noise on power line
to enable high-accuracy sensor
Reduces the footprint of a switching regulator
Enables more compact application / module
36V (Absolute Maximum Ratings 45V) input and synchronous rectification switching regulator (DC-DC converter) adopt the ultra-small package HSNT-6 (2.46mm x 1.96mm).
Suitable for industrial equipment, house facilities and house appliance, the S-8580/1 contributes to downsize the machines or modules.
The gull-wing type package, HTMSOP-8 is recommended when the mountability is required.
There is no need for a large capacitor
Slope compensation circuits and phase compensation circuits in the S-8580/1 Series have been optimized to provide a high transient response.
The external high output capacitors used to compensate for overshoot and undershoot have been downsized, which has also contributed to lowering costs.
External parts to reduce ripple are not required
The S-8581 Series employs a proprietary low-ripple circuit that ensures low ripple without any external parts.
It achieves 9mVp-p across the full load current range including even during PFM control, which is especially prone to ripple.
There is no need to add external parts as a countermeasure to ripple.
