MAX17552BATB+T

MAX17552BATB+T is a 60V, 100mA, ultra-small, high-efficiency, synchronous step-down DC-DC converter with 22μA no-load supply current. It is a high-voltage, Himalaya synchronous step-down DC-DC converter with integrated MOSFETs operating over a 4V to 60V input voltage range. The device offers a programmable switching frequency to optimize solution size and efficiency. Programmable soft-start allows the user to reduce the inrush currents. An EN/UVLO pin allows the user to turn on/off the device at the desired input-voltage level. An open-drain RESET pin allows output-voltage monitoring. Typical applications are industrial sensors and process control, 4mA–20mA current-loop powered sensors, high-voltage LDO replacement, battery-powered equipment, HVAC and building control, and general-purpose point of load.

• Eliminates external components and reduces total cost
• No schottky-synchronous operation for high efficiency and reduced cost, internal compensation
• Fixed internal 5.1ms or programmable soft-start, all-ceramic capacitors, ultra-compact layout
• Reduces number of DC-DC regulators to stock, configurable between PFM and forced-PWM modes
• Reduces power dissipation, PFM feature for high light-load efficiency
• Operates reliably in adverse industrial environments, peak current-limit protection
• Programmable EN/UVLO threshold, monotonic startup into prebiased output
• Complies with CISPR32 (EN55032) class B conducted and radiated emissions
• 10-pin TDFN-CU-EP package, hiccup overcurrent protection scheme
• Ambient operating temperature range from -40°C to +125°C
