Output voltage control The voltage divided by resistors R1 and R2 is compared with the internal reference voltage by the error amplifier. The amplifier output then drives the P-channel MOSFET connected to the VOUT pin. The output voltage at the VOUT pin is regulated by this negative feedback system. The current limit circuit and short protect circuit operate in relation to output current level. VIN Current Fold-back Protection Vref VOUT AMPLIFIER R1 Vfb Reference Voltage R2 GND 2. Pass transistor The pass transistor with low turn-on resistance used in MD7602 is a P-channel MOSFET. If the potential on VOUT pin is higher than VIN, it is possible that IC will be destroyed due to reverse current which is caused by parasitic diodes between VIN and VOUT. Therefore, the VOUT pin potential exceeds VIN+0.3V is not allowed. 3. Current foldback and over temperature protection The MD7602 series includes a combination of a fixed current limiter circuit and a foldback circuit, which aid the operations of the current limiter and circuit protection. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, output voltage drops further and output current decreases. This design can prevent the chip be damaged due to over temperature, moreover, the heat dissipation is limited by the package type. Special attention should be paid to that the product of the dropout voltage on the chip and the output current must be smaller than the heat dissipation. If power consumption on the chip is more than the heat dissipation, OTP will protect the chip from damaging due to over temperature. ■ Notes: 1. The input and output capacitors should be placed as close as possible to the IC. 2. If the impedance of the power supply is high, which is caused by forgetting installing input capacitor or installing too small value capacitor, the oscillation may occur. 3. Pay attention to the operation conditions of input and output voltage and load current, such that the power consumption in the IC should not exceed the allowable power consumption of the package even though the chip has short circuit protection. 4. IC has a built-in anti-static protection (ESD) circuit, but please do not add excessive stress to the IC. 8 / 12 ■ PACKAGING INFORMATION 9 / 12 ■ PACKAGING INFORMATION(Continued) 10 / 12 ■ PACKAGING INFORMATION(Continued) 11 / 12 ■ PACKAGING INFORMATION(Continued) For the newest datasheet, please see the website: www.md-ic.com.cn Version V1.6 20210930 12 / 12
