| MB3800 Switching Regulator Controller The MB3800 is a single-channel switching regulator control IC for low voltage applications incorporating a soft start function and short circuit detection function. The device has a low minimum operating voltage of V and is ideal for the power supply of battery-operated electronic equipment. • Wide supply voltage operating range V to 15 V • Low current consumption Typically mA in operation, 1 uA or less in stand-by • High speed operation is possible Maximum 1 MHz • The error amplifier gain is set inside the IC, so peripheral components are minimized. • Incorporates a soft start circuit. • Incorporates a timer-latch type short circuit detection circuit SCP . • Totem-pole type output with adjustable on/off current for NPN transistors • Incorporates a stand-by function. • Two types of packages SOP-8 2 types Application • LCD monitor/panel • Power supply module • Portable apparatus etc. • San Jose, CA 95134-1709 • 408-943-2600 MB3800 Contents Description 1 Features 1 Application 1 Pin Assignment 3 Pin Description 3 Block Diagram 4 Absolute Maximum Ratings 4 Recommended Operating Conditions 5 Electrical Characteristics 6 Diagram 7 How to Set the Time Constant for Soft Start and Short Circuit Detection 8 Soft Start 8 Short Circuit Protection 8 Typical Characteristics 9 Functional Description 12 Switching Regulator Function 12 Power Supply Control Function 12 Other Functions 13 Application Example 13 Notes On Use 14 Ordering Information 14 RoHS Compliance Information 14 Package Dimensions 15 Document History 17 Sales, Solutions, and Legal Information 18 Page 2 of 18 MB3800 Pin Assignment IN SCP VCC BR/CTL TOP VIEW SOE008 SOB008 Pin Description Pin No. 1 2 3 4 5 6 7 8 Symbol SCP VCC BR/CTL OUT GND OSC FB I Error amplifier inverting input pin Soft start and SCP setting capacitor connection pin Power supply pin I Output current setting and control pin O Totem-pole type output pin Ground pin Capacitor and resistor connection pin for setting the oscillation frequency O Error amplifier output pin Page 3 of 18 Block Diagram MB3800 Reference voltage supply 36 kΩ Error Amp 500 Ω Sawtooth wave oscillator V PWM Comp. + + + DTC V Output drive control circuit 6 GND Soft start SCP 2 SCP 4 BR/CTL OUT 5 30 kΩ Absolute Maximum Ratings Parameter Power supply voltage Output source current Output sink current Allowable dissipation Ordering Information Part Number MB3800PF-❏❏❏E1 MB3800PNF-❏❏❏E1 Package 8-pin Plastic SOP SOE008 8-pin Plastic SOP SOB008 Remarks RoHS Compliance Information The LSI products of Cypress with “E1” are compliant with RoHS Directive , and has observed the standard of lead, cadmium, mercury, Hexavalent chromium, polybrominated biphenyls PBB , and polybrominated diphenyl ethers PBDE The product that conforms to this standard is added “E1” at the end of the part number.
