Description
- DESCRIPTION
- The TPS51125A is a cost effective, dual-synchronous buck controller targeted for notebook system power supply solutions. It provides 5-V and 3.3-V LDOs and requires few external components. The 270-kHz VCLK output can be used to drive an external charge pump, generating gate drive voltage for the load switches without reducing the main converter’s efficiency.
- FEATURES
- • Wide Input Voltage Range: 5.5 V to 28 V
- • Output Voltage Range: 2 V to 5.5 V
- • Built-in 100-mA 5-V/3.3-V LDO with Switches
- • Built-in 1% 2-V Reference Output
- • With/Without Out-of-Audio™ Mode Selectable
- Light Load and PWM only Operation
- • Internal 1.6-ms Voltage Servo Softstart
- • Adaptive On-Time Control Architecture with
- Four Selectable Frequency Setting
- • 4500 ppm/°C R
- DS(on)
- Current Sensing
- • Built-In Output Discharge
- • Power Good Output
- • Built-in OVP/UVP/OCP
- • Thermal Shutdown (Non-latch)
- • QFN24 (RGE)
