TA76524P

The TA76524P is an IC developed for constant voltage power supply by switching system. This switching regulator assures high level of conversion efficiency. There are some features as follows. First is pulse width modulation (PWM) system. Secondly, output in single-end or push-pull system is possible. Then is low current consumption at no-load which is 5 mA (standard). The last one is compatible with SC3524.

What comes next is about the absolute maximum ratings of TA76524P (Ta=25). The VCC (supply voltage) is 40 V. The IC (collector output current) is 100 mA. The IREF (reference output current) is 50 mA. The ICT (CT terminal current) is 5 mA. The PD (power dissipation) is 750 mW. The storage temperature is from -55 to +125. The operating temperature is from -30 to +75.

The following is about the TA76524P electrical characteristics (VCC=20 V, f=20 kHz, Ta=25). Here is about the error amplifer unit. The typical VIO (input offset voltage) is 2 mV and the maximum is 10 mV at VIC=2.5 V. The typical II (input bias current) is 1A and the maximum is 10A at VIC=2.5 V. The minimum GVO (open loop voltage gain) is 60 dB and the maximum is 80 dB. The minimum MVIN (common mode input voltage range) is 1.8 V and the maximum is 3.4 V at Ta=25. The typical CMRR (common code rejection ratio) is 70 dB. The typical BW (bandwidth) is 3 MHz. The minimum VOp-p (output voltage swing) is 0.5 V and the maximum is 3.8 V Ta=25.
