                      Product Overview

                      The MAX735EPA+ is a -5V, negative output, inverting, current mode PWM DC to DC converter in 8 pin DIP package. This CMOS inverting switch mode regulator has internal power MOSFET. It operates from 4V to 6.2V input, output current 200mA (minimum) and 275mA (typical) is provided for inputs greater than 4.5V. The quiescent supply current is typically 1.6mA and shutdown mode reduces this to 10μA. These power conserving features along with high efficiency and application circuits that lend themselves to miniaturization make the device idle for broad range of on-card applications. It employs high performance current mode pulse width modulation (PWM) control scheme to provide tight output voltage regulation and low subhormonic noise. The regulator is production tested in actual applications circuits and output accuracy is ±5% over all specified condition of line, load and temperature. It is used in board level Dc to DC conversion, battery powered equipment and computer peripherals.

                      • Output voltage of -5V
                      • Operating temperature range from -40°C to 85°C
                      • 1W output power (Vin ≥ 4.5V)
                      • 78% typical efficiency at Iload = 100mA
                      • Soft-start, low noise and jitter
                      • Simple application circuit
                      • Line regulation of 0.1%/V (V+ = 4V to 6.2V) and load regulation of 000.1%/mA (Iload = 0mA to 200mA)
                      • Fixed frequency oscillator is factory trimmed to 160KHz allowing for easy noise filtering
