5 / 8 page 5 GM2574 1.5A STEP DOWN VOLTAGE SWITCHING REGULATORS Electrical Characteristics: All Output Voltage Versions (Specifications with standard type face are for T = 25℃, and those with bold face type apply over full Operating Temperature rage) Parameter Condition Symbol Min Typ Max Unit 100 Feedback Bias Current VFB =5V (Adjustable Version Only) Ib - 50 500 nA Oscillator Frequency (Note 3) fo 42 52 58 kHz 1.8 Saturation Voltage lOUT = 1.5A (Notes 4, 5) VSAT - 1.4 2.0 V Max Duty Cycle (ON) (Note 5) DC 93 98 - % 3.6 6.9 Current Limit Peak Current (Notes 4, 5) lCL 3.4 4.5 7.5 A Output =0V (Notes 4, 6) 2 Output Leakage Current Output = -1V (Notes 4, 6) lL - 7.5 30 mA Quiescent Current (Note 6) lQ - 5 10 mA Standby Quiescent Current SD Pin = 5V (OFF) lSTBY - 50 200 µA 1.0 Low (ON) VIH - 1.2 0.8 2.2 SD Pin Logic lnput Level High (OFF) VIL 2.4 1.4 - V VLOGlC = 2.5V (OFF) IH 12 30 µA SD Pin lnput Current VLOGlC = 0.5V (ON) IL 0 10 Note 1: Stresses greater than those listed under Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. Note 2: The human body model is a 100pF capacitor discharge through a 1.5KΩ resistor into each pin. Note 3: External components such as the catch diode, inductor, input and output capacitors, and voltage programming resistors can affect switching regulator system performance. Where the GM2574 is used as shown in Figure 1&2 test circuits. Note 4: No diode, inductor or capacitor connected to output pin. Note 5: Feedback pin removed from output and connected to 0V to force the output transistor switch ON. Note 6: Feedback pin removed from output and connected to 12V for the 3.V, 5V and Adj version, to force the output transistor switch OFF. |
