TPS62933PDRLR 3.8V to 30V, 3A Synchronous Buck Converter
The TPS62933PDRLR is a high-efficiency, compact synchronous buck converter designed by Texas Instruments (TI) for applications requiring wide input voltage flexibility and precise output regulation. Operating from a 3.8V to 30V input range, it delivers up to 3A continuous output current with an adjustable output voltage range of 0.8V to 22V, making it ideal for industrial automation, portable electronics, and distributed power systems. The device integrates 76mΩ (high-side) and 32mΩ (low-side) MOSFETs, enabling a 98% maximum duty cycle for optimal efficiency at low input voltages. Its 200kHz to 2.2MHz adjustable switching frequency allows designers to optimize solution size, efficiency, and EMI performance, while the ultra-low quiescent current (12µA typical) extends battery life in low-power modes. The converter supports pulse frequency modulation (PFM) for light-load efficiency and features soft-start control via an external capacitor to minimize inrush current.
Key Features & Technical Highlights
The TPS62933PDRLR employs a fixed-frequency peak current control mode for fast transient response and excellent line/load regulation, eliminating the need for external compensation components. Its integrated frequency spread spectrum (FSS) reduces EMI emissions, ensuring compliance with standards like CISPR-22. The device includes non-latching protections for over-temperature (OTP), over-current (OCP), over-voltage (OVP), under-voltage (UVP), and under-voltage lockout (UVLO), with hiccup mode recovery for fault conditions. The precision enable (EN) threshold simplifies power sequencing, while cycle-by-cycle current limiting safeguards MOSFETs during overload events. For applications requiring pre-biased output startup, the device supports seamless transition without latch-up. The operating junction temperature range (-40°C to 150°C) and RoHS-compliant, lead-free SOT-583 package ensure reliability in harsh environments.
