High Efficiency 1.5MHz, Step Up Regulator
DATASHEET
TD8210
General Description
Features
The TD8210 is a fixed switching frequency (1.5MHz typical),
Wide 2.7V to 6V Input Voltage Range
current-mode, step-up regulator with an integrated N-channel
Built-in 0.2Ω N-Channel MOSFET
MOSFET. The device allows the usage of small inductors and
Built-in Soft-Start
output capacitors for portable devices. The current-mode control High Efficiency up to 90%
scheme provides fast transient response and good output voltage <1mA Quiescent Current During Shutdown
accuracy.
Current-Mode Operation
The TD8210 includes under-voltage lockout, currentlimit,and
Stable with Ceramic Output Capacitors
over-temperature shutdown preventing damage in the event of an Fast Transient Response
output overload.
Current-Limit Protection
Over-Temperature Protection with Hysteresis
Available in a SOT-23-5A and TDFN2x2-6 Package
Lead Free and Green Devices Available
(RoHS Compliant)
Applications
Cell Phone and Smart Phone
PDA, PMP, MP3
Digital Camera
Boost Regulators
