24-PIN PLASTIC SSOP  
DESCRIPTION  
The MB3788 is a dual-channel PWM-type switching regulator controller; it in-  
corporates a reference voltage.  
The MB3788 has a PWM circuit and an output circuit as well as a reference  
voltage power supply with a voltage accuracy of ±1%. The maximum operating  
frequency is 1 MHz. It is designed for a voltage-drop output switching regulator  
suitable for a logic power supply or speed control of a DC motor.  
The MB3788 is compatible with all master ICs producing triangular waves, saw-  
tooth waves and sine waves with an amplitude of 1.3 to 1.9 V.  
It can be used in high-performance portable equipment such as a video cam-  
corder or notebook personal computer (word processor).  
FEATURES  
- Wide operating power supply voltage range: 3.6 to 18 V  
- Low power dissipation  
- Operating: 1.9 mA (standard)  
Standby: 10 µA max.  
- High-frequency operation: 100 kHz to 1 MHz  
- On-chip timer and latch-type short-circuit detection circuit  
- Wide error amplifier input voltage range: -0.2 V to VCC - 1.8 V  
- On-chip high-accuracy reference voltage circuit: 2.50 V ±1%  
- Output circuit  
(FPT-24P-M03)  
PNP transistor drive output pin: Push-pull type  
ON/OFF current values set independently  
- On-chip standby function and output control function  
- High-density packaging: SSOP-24P  
This device contains circuitry to protect the inputs against  
damage due to high static voltages or electric fields. However,  
it is advised that normal precautions be taken to avoid appli-  
cation of any voltage higher than maximum rated voltages to  
this high impedance circuit.
