The MP3361 is a fast, highly efficient and
precision high voltage Xenon photo-flash
charger for Digital Still Cameras (DSC).
The MP3361 features a 1A peak current and
charges to 300V in 4 seconds from 4.2V battery
voltage. A 60V, 0.5Ω internal power switch
lowers transformer turns ratio and switching
losses associated with the primary leakage
inductance and winding capacitance. Integrated
secondary feedback resistors provide +/-3%
output voltage charge accuracy.

1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.

MP3361 – 300V, 1A PEAK INTEGRATED PHOTO FLASH CHARGER AND IGBT DRIVER
OPERATION
The MP3361 controlled flyback charger operates
in critical conduction mode. The Output voltage is
divided down through an internal 300: 1 resistive
divider from the positive terminal of the
transformer secondary, (FB pin) and compares it
with an internal 1.2V reference. The low to high
transition of the CHG pin will enable the flyback
converter to switch.
blanking for turn off transition. The circuit will stop
switching and RDYB will be pulled low once the
flash capacitor is charged to 300V, a value set by
the internal 300:1 R divider and 1.2V reference.
When the charge is full, the part will shut down its
internal circuitry with less than 1uA drawn from
VIN. Toggling the CHG pin will start the charge
cycle again. Bringing CHG pin low terminates the
power delivery and puts the part in shutdown. A
maximum TON timer prevents pulling current from
a depleted battery. If the ON time exceeds
maximum TON, the switch is forced OFF
regardless of IPEAK detection.
A constant TOFF of 20μs is used when the output
voltage is below 20V to avoid inrush current. The
boundary mode operation will follow to minimize
charge time when the output voltage is above
20V. A minimum TOFF of 200ns serves as
