Description
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.
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
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.
