The MAX736/737/739/759 PWM regulator refers to the CMOS countercurrent switched regulator that has an interior power MOSFET. Fixed output voltage of MAX736/737/739 are -12V,-15V and -5V respectively. Input voltage range of MAX759 is +4V~+15V, output voltage range is 0~+15V. If the input voltage is +4.5V, output power will be 1.25W, and when it ascends to +12V, output power will be 2.5W. Typical value of static current of MAX739 is 1.7mA. In a power-off state, the current is 1μA. Typical value of efficiency is 83%. 156-kHz current PWM has an undervoltage lock and a soft-start protection device.
