Maxim Integrated (MAX15062AATA+T) DC/DC Controller, Synchronous Buck

DC/DC Controller, Synchronous Buck (Step Down), 4.5 V to 60 V, 1 Output, 500 kHz, TDFN-8 Product Overview The MAX15062AATA+T is an ultra small, high efficiency, synchronous step-down DC-DC converter in 8 pin TDFN package. It has a peak current mode control architecture with a MODE pin that can be used to operate device in pulse-width modulation (PWM) or pulse-frequency modulation (PFM) control schemes. PWM operation provides constant frequency operation at all loads & is useful in applications sensitive to variable switching frequency. PFM operation disables negative inductor current & additionally skips pulses at light loads for high efficiency. The low-resistance on-chip MOSFETs ensure high efficiency at full load & simplify PCB layout. To reduce input inrush current device offers an internal soft-start. The device also incorporates an EN/UVLO pin that allows user to turn on part at desired input-voltage level. An open-drain RESET(complementary) pin can be used for output-voltage monitoring. It is used in HVAC & building control, 4mA to 20mA current loops & general purpose point of load. Supply voltage range is 4.5V to 60V Automotive operating temperature range from -40°C to 125°C Eliminates external components & reduces total cost, internal compensation & internal soft-start Reduces number of DC-DC regulators to stock, fixed 3.3V output voltage option Delivers up to 300mA load current, shutdown current is 2.2µA (typ) Reduces power dissipation, peak efficiency is 92%, PFM feature for high light-load efficiency Switching frequency is 500KHz and maximum duty cycle is 91.5%(typ) All ceramic capacitors, ultra compact layout & overtemperature protection Monotonic start-up into pre-biased output Applications Power Management, Industrial Product Information Supply Voltage Min: 4.5V Supply Voltage Max: 60V No. of Outputs: 1 Output Duty Cycle (%): 91.5% Controller IC Case Style: TDFN No. of Pins: 8Pins Switching Frequency: 500kHz Topology: Synchronous Buck (Step Down) Operating Temperature Min: -40°C Operating Temperature Max: 125°C Product Range: Himalaya Series MSL: MSL 1 - Unlimited
