Switching Voltage Regulators -12V, Inverting, PWM, Current-Mode DC-DC Converter
The MAX736/MAX737/MAX739/MAX759 are CMOS，inverting，switch-mode regulators with an internal power MOSFET.Guaranteed output power for the MAX739 is 1.25Wwhen powered from a+4.5V input, and 1.5W when powered from +6V. Quiescent supply current for the MAX739 is typically 1.7mA, and a shutdown mode reduces this to 1uA.These power-conserving features, along with high efficiency and an application circuit that lends itself to miniaturization, make these parts excel in a broad range of on-card and portable equipment applications.
The MAX736/MAX737/MAX739 have fixed outputs of -12V, -15V, and-5V respectively.TheMAX759 is adjustable from OV to-15V.Output voltages beyond -15V require a transformer.
These inverting DC-DC converters employ a high-performance, current-mode, pulse-width modulation (PWM)control scheme to provide tight output voltage regulation and low noise.The fixed-frequency oscillator is factory-trimmed to 165kHz,allowing easy noise filtering.The devices are production tested in an actual application circuit, and output accuracy is guaranteed at +5% over all specified conditions of line, load,and temperature.
The input voltage range is+4Vto+15V.For similar devices with smaller packages and an input voltage range of +4V to +11V, refer to the MAX735/MAX755 data sheet.
