30-A, 15-V synchronous buck converter delivers 90-percent efficiency
The TPS53355 converter delivers high performance to low-output voltage, high-current applications that demand increased power density, such as notebook computers, embedded computers, servers, storage and telecommunication systems.
The TPS53355 30-A regulator uses a D-CAP mode control feature to achieve a transient response of up to 2 A/µs , which is 20-percent faster than other solutions that use current or voltage mode control. The D-CAP mode control also minimizes the use of external components and requires no loop compensation.
The TPS53355 delivers high efficiency and performance: input voltage range up to 15 V; 90-percent efficiency at 30-A, 12 Vin, 1.5 Vout at 500 kHz. The device offers accurate power delivery with 1 percent voltage regulation accuracy.
The TPS53355 is available in a 22-pin, 5-mm x 6-mm QFN PowerStack package. Pricing is $4.65 in 1,000-unit quantities.
