TB2921HQ Product details

Description

is made only on the single channel.) 1. Standby SW Function (pin 4) By means of controlling pin 4 (standby pin) to High and Low, the power supply can be set to ON and OFF.The threshold voltage of pin 4 is set at about 3VBE (typ.), and the power supply current is about 2 µA (typ.) in the standby state.VCC ON Power OFF 4 10 kΩ ≈ 2 VBE to BIAS CUTTING CIRCUIT Control Voltage of Pin 4: VSB Standby ON OFF Power OFF ON VSB (V) 0~0.5 2.5~6 V When changing the time constant of pin 4, check the pop

Features

High power output : POUT MAX (1) = 50 W (typ. ) (VCC = 15.2 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT MAX (2) = 43 W (typ. ) (VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω) POUT MAX (3) = 80 W (typ. ) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 2 Ω) : POUT (1) = 29 W (typ. ) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω) : POUT (2) = 25 W (typ. ) (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω).
Low distortion ratio: THD = 0.01.
