MCP1650/51/52/53

750 kHz Boost Controller

Description

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)

• 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.
