Notes:
3. For correct operation SGND and PGND should always be connected together.
4. Measured on “High Effective Thermal Conductivity Test Board" according to JESD51.
5. Device starts up above 5.4V and as such the minimum applied supply voltage has to be above 5.4V (plus any noise margin). The ZXLD1371 will,
however, continue to function when the input voltage is reduced from ≥ 8V down to 5.0V.
When operating with input voltages below 8V the output current and device parameters may deviate from their normal values; and is dependent
on power MOSFET switch, load and ambient temperature conditions. To ensure best operation in Boost and Buck-boost modes with input
voltages, V IN , between 5.0 and 8V a suitable boot-strap network on V AUX pin is recommended.
Performance in Buck mode will be reduced at input voltages (V IN , V AUX ) below 8V. – a boot-strap network cannot be implemented in buck mode.
6. V AUX can be driven from a voltage higher than V IN to provide higher efficiency at low V IN voltages, but to avoid false operation; a voltage should
not be applied to V AUX in the absence of a voltage at V IN . V AUX can also be operated at a lower voltage than V IN to increase efficiencies at high
V IN .
7. The device contains circuitry to control the switching frequency to approximately 400kHz. The maximum and minimum operating frequency is not
tested in production.
