6 / 38 page  LM2588 SNVS117D – APRIL 1998 – REVISED APRIL 2013 www.ti.com LM2588-12 Electrical Characteristics Specifications with standard type face are for TJ = 25°C, and those in bold type face apply over full Operating Temperature Range. Unless otherwise specified, VIN = 5V. Symbol Parameters Conditions Typical Min Max Units SYSTEM PARAMETERS Test Circuit of Figure 19(1) VOUT Output Voltage VIN = 4V to 10V 12.0 11.52/11.40 12.48/12.60 V ILOAD = 300 mA to 1.2A ΔVOUT/ Line Regulation VIN = 4V to 10V 20 100/200 mV ΔVIN ILOAD = 300 mA ΔVOUT/ Load Regulation VIN = 10V 20 100/200 mV ΔILOAD ILOAD = 300 mA to 1.2A η Efficiency VIN = 10V, ILOAD = 1A 90 % UNIQUE DEVICE PARAMETERS(2) VREF Output Reference Measured at Feedback Pin 12.0 11.79/11.76 12.21/12.24 V Voltage VCOMP = 1.0V ΔVREF Reference Voltage Line VIN = 4V to 40V 7.8 mV Regulation GM Error Amp ICOMP = −30 μA to +30 μA 0.328 0.186 0.621 mmho Transconductance VCOMP = 1.0V AVOL Error Amp Voltage VCOMP = 0.5V to 1.6V 70 41/21 V/V Gain RCOMP = 1.0 MΩ (3) (1) External components such as the diode, inductor, input and output capacitors can affect switching regulator performance. When the LM2588 is used as shown in Figure 18 and Figure 19, system performance will be as specified by the system parameters. (2) All room temperature limits are 100% production tested, and all limits at temperature extremes are specified via correlation using standard Statistical Quality Control (SQC) methods. (3) A 1.0 M Ω resistor is connected to the compensation pin (which is the error amplifier output) to ensure accuracy in measuring AVOL. 6 Submit Documentation Feedback Copyright © 1998–2013, Texas Instruments Incorporated Product Folder Links: LM2588 |
