JAJSJP4A August 2017 – September 2020 LV14360
PRODUCTION DATA
The LV14360 regulator is an easy-to-use step-down DC-DC converter that operates from a 4.3-V to 60-V supply voltage. The device integrates a 155-mΩ (typical) high-side MOSFET and is capable of delivering up to 3-A DC load current with exceptional efficiency and thermal performance in a very small solution size. The operating current is typically 300 μA under no load condition (not switching). When the device is disabled, the supply current is typically 1 μA. An extended family is available in 1-A and 2-A load options in pin-to-pin compatible packages.
The LV14360 implements constant frequency peak current mode control with sleep mode at light load to achieve high efficiency. The device is internally compensated, which reduces design time, and requires fewer external components. The switching frequency is programmable from 200 kHz to 2 MHz by an external resistor RT. The LV14360 is also capable of synchronization to an external clock within the 250-kHz to 2 MHz frequency range, which allows the device to be optimized to fit small board space at higher frequency, or high efficient power conversion at lower frequency.
Other features are included for more comprehensive system requirements, including precision enable, adjustable soft-start time, and approximate 90% duty cycle by BOOT capacitor recharge circuit. These features provide a flexible and easy-to-use platform for a wide range of applications. Protection features include over temperature shutdown, VOUT overvoltage protection (OVP), VIN undervoltage lockout (UVLO), cycle-by-cycle current limit, and short-circuit protection with frequency foldback.
