ZMDI announces three new addition to its ZSPM15xx True-Digital PWM Controller Family


ZMDI, a global semiconductor company, announces the new ZSPM1511, ZSPM1512 and ZSPM1513 to extend the ZSPM15xx True-Digital PWM Controller Family for simplifying designs and accelerating time-to-market.

ZMDI has released the ZSPM1511, ZSPM1512 and ZSPM1513 single–phase, true–digital pulse-width modulator (PWM) power controllers optimized for non-isolated point-of-load (POL) applications.

The ZSPM1511, ZSPM1512 and ZSPM1513 are pre-configured to provide customers with a fast time-to-market and easy-to-design solution for high-performance, digitally controlled power supplies with one of ZMDI’s integrated MOSFET power stage DrMOS products: the ZSPM9000, ZSPM9010, ZSPM9015 or ZSPM9060. ZSPM15xx controllers feature a flexible design that allows users to easily select the over-current protection limit, output voltage rise time and control-loop compensation via two external resistors to achieve the highest performance.

ZSPM15xx controllers are preconfigured for the power stage output: the ZSPM1511 output is 0.85V; ZSPM1512 output is 1.00V; and ZSPM1513 output is 1.20V. All three new products are capable supporting up to a maximum load current of 15A.
