The devices are suitable for single lithium-ion, multicell alkaline or NiMH applications where the output voltage is within the battery voltage range.

The switching frequencies up to 1.5MHz could be fixed by an external resistor. Also the oscillator could be synchronized to an external clock. The quiescent current is 1mA which maximizes the

battery life in portable applications. Other features include a 1μA shutdown, thermal shutdown and current limit. The TCS3812 is available in the 8-pin thermally enhanced SOP package (or upon request).

The TCM3651implements the BuckBoost converter with a single inductorarchitecture that operates with input voltagesabove, below orequal to the output voltage.And support 2-switch boost mode for higherefficiency.
The integrated low Rds(on) MOSFET minimizesphysical footprint, maximizes efficiency, whichreduces the power dissipation. Constant currentcontrol is utilized to protect the device fromovershooting at fault conditions. Built-in loopcompensation simplifies the circuit and design.TCM3651 guaranteesrobustness withunder voltage lockout, short circuitprotection and thermal protection.
