With 20ns minimum on-time capability, the converter is capable of large input-to-output conversion ratios. Voltage quality can be monitored by observing the PGOOD signal. The devices can operate in dropout by running at 99% duty cycle, making them ideal for automotive and industrial applications. The devices offer two fixed output voltages of 5V and 3.3V. In addition, the devices can be configured for 1V to 10V output voltages using an external resistor-divider. Frequency is internally fixed at 2.1MHz, which allows for small external components and reduced output ripple, and guarantees no AM interference. The devices offer pin-enabled spread-spectrum-frequency modulation designed to minimize EMI-radiated emissions due to the modulation frequency.The MAX20075/MAX20076 /MAX25276 are available in small (3mm × 3mm) 12-pin TDFN and side-wettable TDFN packages with an exposed pad, and use very few external components.

The LTC2960 is a nano-current, high voltage two-input voltage monitor, ideally suited for multicell battery applications. External resistive dividers configure custom comparator thresholds. The supervisory circuit monitors the ADJ input and pulls the RST output low when the input drops below threshold. A reset timeout period delays the return of the RST output to a high state when the input rises above the threshold. The spare comparator allows voltage conditions to be detected with either a non-inverting input, IN+ (LTC2960-1/LTC2960-3) or an inverting input, IN– (LTC2960-2/LTC2960-4). A manual reset (MR) input is provided for external activation of the reset output.Other options provided on the LTC2960-1/LTC2960-2 include a reset timeout period select pin, RT, to select between 15ms or 200ms reset timeout periods. The LTC2960-3/LTC2960-4 have a fixed 200ms reset timeout period. The RST and OUT outputs are available with active pull-up circuits to an output logic supply pin (LTC2960-3/LTC2960-4) or 36V open-drain outputs (LTC2960-1/LTC2960-2).Applications Portable Equipment Battery Powered Equipment Security Systems Automotive Systems
