IFJM-001

IFJM-001 PWM Amplifier Module IFJM - 001 is an amplifier module that linearly drives a piezo actuator with high efficiency. The maximum output is ± 60 V. The output stage bus voltage can be continuously varied in the range of ± 25 V to ± 60 V according to the assumed maximum output, so efficiency of amplifier can be optimized according to the actuator used. 　Outline 10pins DIP module　（Refer to dimension on Page2） 58mm(W) x 32mm(L) x 15mm(H)　Not include connection pin 　Function High voltage amplifier Applications Driving piezo actuator or high impeadance speaker Output voltage 0V～±60V （Output power stage bus voltage ±25V～±60V ） 　Absolute maximum ratings MIN MAX UNIT Supply Voltage　12V (Pin7-Pin6) -0.3 13 V Supply Voltage　+5V (Pin3-Pin2) -0.3 5.5 V Supply Voltage　-5V (Pin4-Pin2) -5.5 0.3 V Input Voltage　VIN (Pin1-Pin2) -5 5 V Boost Voltage　VB (+B to -B) 50 125 V Operating temperature range (Ta) -25 55 ℃ 　Functional Summary Function 　Over temparture protection 　 OTP Purpose Protection of Module 　Reset 　 CSD External control of oscillation 　Adjustable bus voltage 　 CTL Control of VB Operation When the temperature sensor on the board exceeds 75℃, the voltage of the CSD pin shifts from VAA level to GND level and oscillation stops. Oscillation restore at 65℃. Operating: VAA level, Heating protection: GND level, Abnormal: VSS level Forced oscillation stop: Fixed at VSS level or more and GND level or less. Amplifier output stage bus voltage (VB) can be varied by resistor added between CTL and 0 V terminals. Lower bus voltage can improve reactive power and EMI. -1- Rev.1.0 　Electrical characteristics 　Ta=25℃　Pin7-Pin6=12V　Pin3-Pin2=+5V　Pin4-Pin2=-5V　　fsw=150kHz Symbol Parameter Conditions MIN TYP MAX UNIT ±60 V Vo Maximum Output Voltage C L =0.1uF VB=±25V to ±60V Io max Maximum Output Current RL=100Ω VB =±25V to ±60V Io peak Maximum Output Current RL=10ΩVB =±25V to ±60V 650 mA THD Total Harmonic Distortion f=1kHz Vo=35Vrms　VB=±60V -80 dB fc LPF Cutoff Frequency VB=±25V to ±60V Von Residual Noise BW=20kHz C L =0.1uF VB=±25V to ±60V Vdc Output DC Voltage VB=±25V to ±60V OTC Over Temperature Protection VB=±25V to ±60V Vpop Power ON/OFF　Output Pop Noise VB=±25V to ±60V I CC 12V Quiescent Power Supply Current VB=±60V I AA +5V Quiescent Power Supply Current I SS -5V Quiescent Power Supply Current ±25 ±250 mA 23k Hz 1 mV ±10 mV 80 ℃ ±5 Vpeak 150 200 mA VB=±25V to ±60V 8 11 mA VB=±25V to ±60V 8 11 mA 70 75 Dimensions （Top View） ◆ Important Note ◆ ●This product was not designed for use with devices which could cause personal injury in the event of failure or malfunction, including devices for use in areas including medical, military, aviation, aerospace, nuclear control, other types of safety mechanisms, etc., or for use in devices which require a high standard of safety.
