Product Summary

The max774csa inverting switching regulator delivers high efficiency over three decades of load current. A unique current-limited, pulsefrequency- modulated (PFM) control scheme provides the benefits of pulse-width modulation (high efficiency with heavy loads), while using less than 100μA of supply current (vs. 2mA to 10mA for PWM converters). The result of the max774csa is high efficiency over a wide range of loads. Applications are (1)LCD-Bias Generators; (2)High-Efficiency DC-DC Converters; (3)Battery-Powered Applications; (4)Data Communicators.

Parametrics

max774csa absolute maximum ratings: (1)V+ to OUT : 21V; (2)V+ to GND : -0.3V, +17V; (3)OUT to GND : -0.3V, to -17V; (4)REF, SHDN, FB, CS: -0.3V to (V+ + 0.3V); (5)EXT : (VOUT - 0.3V)to (V+ + 0.3V); (6)Continuous Power Dissipation (TA = +70°C); (7)Plastic DIP (derate 9.09mW/°C above +70°C): 727mW; (8)SO (derate 5.88mW/°C above +70°C): 471mW; (9)CERDIP (derate 8.00mW/°C above +70°C): 640mW; (10)Operating Temperature Ranges: 0°C to +70°C; (11)Maximum Junction Temperatures: +150°C; (12)Storage Temperature Range : -65°C to +160°C; (13)Lead Temperature (soldering, 10sec): +300°C.

Features

max774csa features: (1)Low-voltage operation and single power supply drive enabled (Single power supply: 4 to 32V, dual power supply: ±3 to ±16V); (2)Low noise level. (Vn = 1.0mVrms typ. : RIAA); (3)High slew rate. (SR = 3V / ms, GBW = 10MHz typ.); (4)Low offset voltage. (VIO = 0.5mV typ.); (5)High gain and low distortion. (GVO = 110dB, THD = 0.0015%); (6)Pin connections are the same as with standard dual operational amplifiers, and outstanding characteristics make these products compatible with the 4558 and 4560 models.
