ZHCSF41B December 2015 – March 2021 LMR16030
PRODUCTION DATA
The LMR16030 SIMPLE SWITCHER® regulator is an easy-to-use step-down DC-DC converter that operates from a 4.3-V to 60-V supply voltage. It 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 40 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 LMR16030 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 2.5 MHz by an external resistor RT. The LMR16030 is also capable of synchronization to an external clock within the 250-kHz to 2.3-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 included for more comprehensive system requirements are precision enable, adjustable soft-start time, and approximately 97% duty cycle by aBOOT capacitor recharge circuit. These features provide a flexible and easy-to-use platform for a wide range of applications. Protection features include overtemperature shutdown, VOUT overvoltage protection (OVP), VIN undervoltage lockout (UVLO), cycle-by-cycle current limit, and short-circuit protection with frequency foldback.
