MCP1650/51/52/53  
750 kHz Boost Controller  
Description  
M
Features  
• Output Power Capability Over 5 Watts  
• Output Voltage Capability From 3.3V to Over  
100V  
• 750 kHz Gated Oscillator Switching Frequency  
• Adaptable Duty Cycle for Battery or Wide-Input,  
Voltage-Range Applications  
The MCP1650/51/52/53 is a 750 kHz gated oscillator  
boost controller packaged in an 8 or 10-pin MSOP  
package. Developed for high-power, portable applica-  
tions, the gated oscillator controller can deliver 5 watts  
of power to the load while consuming only 120 µA of  
quiescent current at no load. The MCP1650/51/52/53  
can operate over a wide input voltage range (2.0V to  
5.5V) to accommodate multiple primary-cell and single-  
cell Li-Ion battery-powered applications, in addition to  
2.8V, 3.3V and 5.0V regulated input voltages.  
• Input Voltage Range: 2.0V to 5.5V  
• Capable of SEPIC and Flyback Topologies  
• Shutdown Control with I < 0.1 µA (Typical)  
Q
• Low Operating Quiescent Current: I = 120 µA  
• Voltage Feedback Tolerance (0.6%, Typical)  
• Popular MSOP-8 Package  
• Peak Current Limit Feature  
• Two Undervoltage Lockout (UVLO) Options:  
- 2.0V or 2.55V  
• Operating Temperature Range: -40°C to +125°C  
An internal 750 kHz gated oscillator makes the  
MCP1650/51/52/53 ideal for space-limited designs.  
The high switching frequency minimizes the size of the  
external inductor and capacitor, saving board space  
and cost. The internal oscillator operates at two differ-  
ent duty cycles depending on the level of the input volt-  
age. By changing duty cycle in this fashion, the peak  
input current is reduced at high input voltages, reducing  
output ripple voltage and electrical stress on power  
train components. When the input voltage is low, the  
duty cycle changes to a larger value in order to provide  
full-power capability at a wide input voltage range  
typical of battery-powered, portable applications.  
The MCP1650/51/52/53 was designed to drive external  
switches directly using internal low-resistance  
MOSFETs.  
Additional features integrated on the MCP1650/51/52/  
53 family include peak input current limit, adjustable  
output voltage/current, low battery detection and  
power-good indication.  
Q
Applications  
• High-Power Boost Applications  
• High-Voltage Bias Supplies  
• White LED Drivers and Flashlights  
• Local 3.3V to 5.0V Supplies  
• Local 3.3V to 12V Supplies  
• Local 5.0V to 12V Supplies  
• LCD Bias Supply
