Product Description

description
The TPS5120 is a dual channel, high-efficiency synchronous buck controller where the outputs run 180 degrees out of phase, which lowers the input current ripple, thereby reducing the input capacitance cost. The PWM/SKIP pin allows the operating mode to switch from PWM mode to skip mode under light load conditions. The skip mode enables a lower operating frequency and shortens the pulse width to the low-side MOSFET, increasing the efficiency under light load conditions.
Independent Dual-Outputs Operate 180° Out of Phase
Wide Input Voltage Range: 4.5-V –28-V
Adjustable Output Voltage Down to 0.9 V
Pin-Selectable PWM/SKIP Mode for High
Efficiency Under Light Loads
Synchronous Buck Operation Allows up to 95% Efficiency
Separate Standby Control and Overcurrent Protection for Each Channel
Programmable Short-Circuit Protection
Low Supply (1 mA) and Shutdown (1 nA) Current
Power Good Output
High-Speed Error Amplifiers
Sequencing Easily Achieved by Selecting
Softstart Capacitor Values.
5-V Linear Regulator Power Internal IC Circuitry
30-Pin TSSOP Packaging
