Smart Power Module for Partial Switching Converter
Features
General Description
• Very low thermal resistance due to using DBC
FSAB20PH60 is an advanced smart power module of PSC(Partial Switching Converter) that Fairchild has newly developed
and designed mainly targeting low-power application especially
for an air conditioners. It combines optimized circuit protection
and drive IC matched to IGBTs. System reliability is further
enhanced by the integrated under-voltage lock-out and shortcircuit protection function.
• 600V-20A single-phase rectifier bridge diode including two
IGBTs for partial switching converter
• Integrated IC for gate driving and protection
• Divided negative dc-link terminals for current sensing
• Isolation rating of 2500Vrms/min.
Applications
• AC 187V ~ 276V single-phase partial-switching converter of
air-conditioner

printed circuit board. The SPM input signal section integrates 3.3kΩ (typ.) pull-down resistor. Therefore, when using an external filtering resistor, please pay attention to the
signal voltage drop at input terminal.
2. The logic input is compatible with standard CMOS or LSTTL outputs.

Note:
1. To avoid malfunction, the wiring of each input should be as short as possible. (less than 2-3cm)
2. VFO output is open collector type. This signal line should be pulled up to the positive side of the 5V power supply with approximately 4.7kΩ resistance. Please refer to Figure 8.
3. VFO output pulse width should be determined by connecting an external capacitor(CFOD) between CFOD(pin7) and COM(pin2). (Example : if CFOD = 33 nF, then tFO = 1.8ms
(typ.)) Please refer to the note 6 for calculation method.
4. Input signal is High-Active type. There is a 3.3kΩ resistor inside the IC to pull down each input signal line to GND. When employing RC coupling circuits, set up such RC couple
that input signal agree with turn-off/turn-on threshold voltage.
5. To prevent errors of the protection function, the wiring around RSC, RF and CSC should be as short as possible.
6. In the over current protection circuit, please select the RFCSC time constant in the range 3~4 µs.
7. Each capacitor should be mounted as close to the pins as possible.
8. Relays are used at almost every systems of electrical equipments of home appliances. In these cases, there should be sufficient distance between the CPU and the relays.
