TPS51404.5-V to 28-V, quad output buck controller for notebook power | Special Purpose Regulators | 4 | LTB | The TPS5140 is a dc/dc controller that incorporates three synchronous-buck controllers and one nonsynchronous 12-V boost converter on one chip to power the voltage rails needed by notebook peripheral components. On-chip high-side and low-side synchronous rectifier drivers are integrated to drive less expensive N-channel power MOSFETs. The nonsynchronous boost converter includes the N channel power MOSFET and supports 120 mA for the PCMCIA power supply. The outputs are controlled independently and two of the synchronous-buck controllers operate 180 degrees out of phase, with the third lowering the input current ripple and allowing a smaller input capacitance to reduce power supply cost. For higher efficiency under all load conditions, the TPS5140 automatically adjusts each channel from the PWM mode to the skip mode independently. The skip mode enables a lower operating frequency and shortens the pulse width to the low side MOSFETs, thereby increasing the efficiency under light load conditions. To further extend battery life, the TPS5140 features dead-time control and very low quiescent current. Resistorless current protection and the fixed high-side driver voltage simplify the system design and reduce the external parts count.

TPS51427ADual-output synchronous D-CAP synchronous buck controller for notebook power with OOB disabled | Integrated Circuits (ICs) | 2 | Active | The TPS51427A is a dual synchronous step-down controller designed for notebook and mobile communications applications. This device is part of a low-cost suite of notebook power bus regulators that enables system designs with low external component counts. The TPS51427A includes two pulse-width-modulation (PWM) controllers, SMPS1 and SMPS2. The output of SMPS1 can be adjusted from 0.7 V to 5.9 V, while the output of SMPS2 can be adjusted from 0.5 V to 2.5 V. This device also features a low-dropout (LDO) regulator that provides a 5-V/3.3-V output, or adjustable from 0.7-V to 4.5-V output via LDOREFIN. The fixed-frequency emulated adaptive on-time control supports seamless operation between PWM mode under heavy load conditions and reduced frequency operation at light loads for high-efficiency down to the milliampere range. An integrated boost switch enhances the high-side MOSFET to further improve efficiency. The main control loop is the D-CAP™ mode that is optimized for low equivalent series resistance (ESR) output capacitors such as POSCAP or SP-CAP. Advanced ramp compensation minimizes jitter without degrading line and load regulation. RDS(on)current sensing methods offers maximum cost saving.
The TPS51427A supports supply input voltages that range from 5.5 V to 28 V. It is available in the 32-pin, 5-mm × 5-mm QFN package (Green, RoHs- compliant, and Pb-free). The device is specified from -40°C to +85°C.
