Nch Power MOSFET's for DC-DC converter

Industry low On-resistance and high efficient devices

For further information »

Overview

These MOSFET's are most suitable for DC-DC converter circuits, featuring the industry's lowest On-resistance by Panasonic's ultra fine processing technology. Fit in a built-in heat sink and power package (HSO8, HSSO8), these MOSFET's will contribute to both higher efficiency and downsizing. For more higher and larger power requirements, our power packages will provide the solution.

Features

• Industry low On-resistance
• With a built-in heat sink
• Clip type
• Halogen free package

5V/12V type 1ch Step-down Type DC-DC Converters <NN30XXX series>

High efficiency and small packages realizing the miniaturization and lower power consumption

For further information »

Overview

This IC integrated two small MOS-FET with very low on-resistance with high-speed DC-DC controller which employed the hysteretic control system. This IC realizes the small size and small operating voltage range DC-DC converter with high-efficiency. And this also allows the smaller mounting dimension for external parts.

Features

• The industry's top class high-efficiency by low on-resistance FET.
• Smaller mounting area
-Small HQFN package
-Architecture without the needs of phase compensation : reducing the external parts number
-Smaller external parts (inductors and condensers)
• High speed response of hysteretic control suppresses variations in the output voltage
• Variable protecting functions (Low input voltage malfunction prevention, heating, overvoltage protection, over current protection, short protection)
• Slow start time adjustment available
• No power consumption when nonuse by ON/OFF control of enable pins
• Constant operation/non-constant operation of SW frequency selectable : achieving the higher efficiency when low load and noise control

IPD for switching power supply <MIP521A>

Realizing high-efficiency and downsizing

For further information »

Overview

MIP521A is suitable for standby power supplies of TVs, main power supply for white goods, etc. Energy consumption is reduced to less than 30mW (@240V at no load), which makes it easier to meet energy efficiency regulations such as ErP, Energy Star, GB. Newly developed power MOSFET withstanding voltage of 800V realizes the reduction of energy loss by snubber circuit. Built-in frequency jitter function can reduce average EMI noise and get rid of EMI filter cost. Protection function of over voltage/load/temperature can achieve the safety.

Features

• Intermittent control at light load condition
⇒High efficiency at light load
• High power MOSFET withstanding Voltage of 800V
• Frequency jitter function
⇒Reduce average EMI noise and simplify EMI filter design
• Protection function
Overload protection function
⇒Auto Restart (Timer Intermittent operation)
Overvoltage protection function
⇒Latch-up shutdown (VCC pin voltage 30V)
Overtemperature protection function
⇒Auto restart (Shutdown at 140ºC, hysteresis at 70ºC)
