TPS40190DRCR Low-pin count synchronous step-down DC/DC controller

illustrate   Since TPS40190 is a cost-optimized synchronous buck controller that operates in the name of 4.5 V to 15 V and implements a fixed-frequency voltage mode supply. The controller uses an adaptive backcross conduction mechanism to prevent the two high-side and rectified MOSFETs from being turned on at the same time, preventing current from shooting through both MOSFETs. The controller also offers a short-circuit protection threshold, which is a choice of one of three values between the user. The level of protection is set to a single external connection to the ground resistor from the match. During the start-up, the impedance connected to the game is felt, the information is decoded, and one of the three thresholds is selected. When the controller detects a short circuit in the output, two   characteristic   Input operating voltage range: 4.5 V to 15 V Reference 0.591 volts ± 1% Voltage mode control Internal 5-V regulator internal steward, electricity and lighting drive external loads Optional short-circuit protection threshold Pre-biased Ouput safety The fixed switching frequency is 300 kHz Internal soft start Small 3 mm × 3 mm 10-pin SON package For N-channel MOSFET driver bootstraps Adaptive anti-cross conduction Built-in bootstrap diode 1.2 One driver reduces switching losses apply Cable modem user device Digital set-top box Graphics/sound cards Entry-level and mid-range servers
