The SP6123 is a fixed frequency, voltage mode, synchronous PWM controller designed to work from a single 5V or 3.3V input supply, providing excellent AC and DC regulation for high efficiency power conversion. Requiring only few external components, the SP6123 packaged in an 8-pin NSOIC, is especially suited for low voltage applications where cost, small size and high efficiency are critical. The operating frequency is internally set to 300kHz (SP6123) or 500kHz (SP6123A), allowing small inductor values and minimizing PC board space. The SP6123 drives an all N-channel synchronous power MOSFET stage for improved efficiency and includes an accurate 0.8V reference for low output voltage applications.
- Optimized for single supply, 3V to 5.5V applications
- High efficiency: greater than 95% possible
- Accurate fixed 300kHz (SP6123) or 500kHz (SP6123A) frequency operation
- Fast transient response
- Internal soft-start circuit
- Accurate 0.8V reference allows low output voltages
- Resistor programmable output voltage
- Loss-less current limit with high side RDS(ON) sensing
- Hiccup mode current limit protection
- Dual N-channel MOSFET synchronous driver
- Quiescent current: 500µA, 30µA in shutdown
- 8-Pin surface mount package
- Frequency for SP6123A is 500kHz
